The Infineon BSC040N10NS5ATMA1 is an N-channel power MOSFET built on Infineon's OptiMOS 5 platform, rated at 100 V VDS max and 4 mOhm maximum on-resistance, packaged in the SuperSO8 5x6 outline (also referenced as PG-TDSON-8-7 / TDSON EP-8). It delivers up to 100 A continuous drain current at 25 C case temperature (and up to 136 A per the Infineon parametric page), with 2.5 W power dissipation at ambient and 139 W at case temperature, making it one of the lowest-RDS(on) parts in the 100 V class in this footprint. What is an N-channel power MOSFET? A metal-oxide-semiconductor field-effect transistor is the workhorse switching element of modern power electronics. The N-channel variant conducts when the gate is pulled above the source by VGS(th); for power applications, the MOSFET category encompasses low-voltage signal MOSFETs, standard MOSFETs, and high-power MOSFETs, the latter being the relevant hypernym for this part. Within discrete semiconductors, this device sits in the power MOSFET tier optimized for switching converters, motor drives, and synchronous rectification. Key features include the OptiMOS 5 technology generation, which delivers up to 44% output capacitance reduction and up to 43% RDS(on) reduction versus the previous generation, enabling higher switching frequencies and higher system efficiency. The part is optimized for synchronous rectification in switched-mode power supplies, where it serves as the low-side FET. Its low Qg and Qgd support fast turn-on/turn-off transitions, reducing switching losses and allowing designers to shrink magnetics. Typical applications include synchronous rectification in 48 V telecom and server DC-DC point-of-load converters, primary-side switching in telecom bricks, motor drive half-bridges in industrial and automotive 12 V/24 V systems, hot-swap and OR-ing circuits, and battery protection in e-mobility. The part is automotive-grade qualified (AEC-Q101 family), making it suitable for body electronics and powertrain peripherals. When designing with this device, ensure the gate driver can source/sink sufficient peak current to quickly charge Qg and avoid linear-region losses during switching transitions. Thermal management is critical: at high continuous current, use multiple thermal vias under the exposed pad and adequate copper pour on both top and inner layers.

BSC042NE7NS3GATMA1 - 75V N-Ch OptiMOS 3 MOSFET | Infineon
The Infineon BSC042NE7NS3GATMA1 is a 75V N-channel power MOSFET from the OptiMOS 3 family, delivering industry-leading 4.2 mOhm maximum on-state resistance with continuous drain current ratings up to 100 A (Tc) in the compact PG-TDSON-8-1 (SuperSO8 5x6) surface-mount package. Designed specifically for synchronous rectification in switched-mode power supplies, the part combines ultra-low RDS(on) with superior switching performance optimized at 80V technology node. A power MOSFET is a voltage-controlled semiconductor switch that uses an insulated gate to modulate current flow between drain and source terminals. The OptiMOS 3 family represents Infineon's third-generation trench MOSFET platform optimized for low conduction loss and fast switching; it sits within the broader taxonomy of power MOSFET -> discrete semiconductor -> power management. This category is the workhorse of modern DC-DC conversion, motor drive, and hot-swap circuits, where every milliohm of RDS(on) translates directly into watts of conduction loss dissipated as heat. Key electrical characteristics include 4.2 mOhm max RDS(on) at VGS=10V, 75V drain-source breakdown voltage, 19A continuous drain current at ambient (Ta) and 100A at case temperature (Tc), with 2.5W (Ta) and 125W (Tc) power dissipation ratings. The gate threshold is typically 1.7V with VGS ratings of +/-20V maximum. The part integrates an intrinsic body diode optimized for synchronous rectification dead-time conduction, eliminating the need for an external anti-parallel diode in most buck/boost topologies. Architecturally, the device uses Infineon's advanced 80V trench technology shrunk to a 75V rating, delivering simultaneously lowest on-state resistance and superior switching performance. The cell density and gate structure minimize both conduction and switching losses, making it ideal for high-frequency (300 kHz to 1 MHz) SMPS applications. The PG-TDSON-8-1 package provides an exposed drain pad that doubles as the thermal dissipation path, enabling low thermal resistance (approximately 1.0 C/W junction-to-case). Typical applications include synchronous rectification in 48V telecom and server DC-DC converters, high-current buck regulators in computing and graphics cards, motor drive and H-bridge circuits, hot-swap and OR-ing controllers in redundant power systems, and battery management for e-mobility and power tools. The wide safe operating area also suits Class-D audio amplifier output stages. When designing with this MOSFET, place the gate driver within 5mm of the gate pin to minimize parasitic inductance, and use a 10 ohm gate resistor to control ringing. Ensure Tj stays below 150C by sizing the PCB copper pour; at 100A continuous, even 4.2 mOhm dissipates 42W that must flow through the exposed pad into the PCB heatsink.

BSC047N08NS3GATMA1 - 80V 100A 4.7mOhm N-Ch MOSFET | Infineon
The Infineon BSC047N08NS3GATMA1 is an N-channel power MOSFET built on the OptiMOS™ 3 platform, rated for 80 V drain-to-source voltage, 100 A continuous drain current (Tc), and a maximum on-resistance of 4.7 mOhm, housed in the SuperSO8 5x6 (PG-TDSON-8-1) surface-mount package. It is optimized for high-frequency switching and synchronous rectification, combining very low RDS(on) with an excellent gate-charge x RDS(on) figure of merit (FOM) that minimizes conduction and switching losses in DC/DC converters. A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled switching device used to switch and amplify signals in power electronics. The N-channel enhancement mode variant conducts when a positive gate-source voltage is applied. Within the broader taxonomy, this part sits at: power MOSFET → discrete semiconductor → transistor → electronic component. MOSFETs are the workhorse of modern switch-mode power supplies (SMPS), motor drives, and battery protection circuits, where their low on-resistance and fast switching translate directly into higher system efficiency and smaller magnetics. Key features of the BSC047N08NS3GATMA1 include a typical RDS(on) of 4.7 mOhm at VGS=10 V, superior thermal resistance thanks to the exposed SuperSO8 pad, normal-level gate threshold for standard logic drive, 100% avalanche tested ruggedness, and Pb-free plating that is RoHS compliant plus halogen-free per JEDEC qualification. The SuperSO8 outline is pin-compatible with industry-standard SO-8 power packages, enabling drop-in upgrades in legacy boards. Architecturally, the OptiMOS™ 3 generation uses a trench-gate cell design that shrinks the channel length and increases cell density, dropping RDS(on) by roughly 30% compared with the prior OptiMOS™ 2 generation at the same die size. The intrinsic body diode is characterized for synchronous-rectifier duty, so the part can replace external Schottky diodes in many buck and forward converter topologies. Gate charge is balanced against output capacitance to keep switching losses low at 300 kHz to 1 MHz operation. Typical applications include high-frequency DC/DC converters in server and telecom SMPS, synchronous rectification in isolated DC/DC bricks, solar micro-inverter power stages, and 48 V eMobility / mild-hybrid accessory rails. The combination of 80 V rating and 100 A current capability also makes it suitable for hot-swap controllers, OR-ing FETs, and battery management protection MOSFETs in multicell Li-ion packs. In each case the low FOM directly improves light-load and full-load efficiency. When designing with this MOSFET, ensure the gate driver can supply and sink the gate charge within the target switching frequency. A 10 Ohm gate resistor is usually sufficient to damp ringing; thermal layout must include at least 6 cm² of drain copper on a 40 x 40 x 1.5 mm FR4 board to reach the datasheet 125 W Tc rating. Always observe the maximum junction temperature of 175 °C and apply appropriate derating for ambient operation above 25 °C.

It belongs to Infineon's OptiMOS 5 25V/30V family, which sets the benchmark for power density and energy efficiency in both standby and full-load operation by combining ultra-low RDS(on) with minimized gate charge and switching losses. A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled three-terminal semiconductor switch used to efficiently route or modulate current in power-conversion circuits. It sits within the broader hierarchy of discrete semiconductors > transistors > MOSFETs > power MOSFETs, and serves as the synchronous switch in DC-DC converters, the low-side switch in motor drivers, and the load-disconnect element in battery protection. OptiMOS 5 specifically targets high-frequency synchronous buck conversion, where the lowest figure of merit (FOM = RDS(on) × Qg) directly translates into reduced switching losses and higher system efficiency. Key differentiating specifications include an extremely low typical on-resistance that maximizes conduction efficiency at 30 V operation, an ultra-low gate charge that minimizes driver losses at high switching frequencies, and an optimized body diode that reduces reverse-recovery losses in synchronous-rectifier topologies. The PG-TDSON-8-6 package exposes the die to a low thermal-resistance pad, allowing 50 W dissipation when properly soldered to a 1 oz copper thermal land, which is essential for keeping the junction temperature within safe limits at full load. The BSC0501NSIATMA1 uses Infineon's advanced trench-gate OptiMOS 5 process, which combines a refined cell pitch with a low-resistance source metallization to deliver industry-leading figure-of-merit performance. The device is characterized for avalanche operation, has an operating junction temperature range of -55°C to +150°C, and is qualified to JEDEC standards for plastic-package surface-mount reliability, making it suitable for demanding automotive and industrial environments. Typical applications include synchronous-rectifier stages in point-of-load (POL) DC-DC converters for servers and telecom, low-side switches in 24 V industrial motor control, battery-management load switches in 12 V automotive subsystems, and USB Power Delivery (PD) buck-converter high-side FETs. The 30 V drain rating provides comfortable margin for 12 V input rails subject to load-dump transients up to ~35 V. When designing with this MOSFET, prioritize minimizing parasitic source-inductance by using short, wide copper pours on the source pads, and ensure the gate driver can source/sink the peak gate current required at the intended switching frequency. Place a 100 nF ceramic bypass capacitor close to the gate to decouple the high di/dt loop and prevent unwanted ringing. Compared to a standard level-shift MOSFET, the OptiMOS 5 family dramatically reduces dead-time and reverse-conduction losses in half-bridge topologies.

The Infineon BSC0502NSIATMA1 is an N-channel power MOSFET built on the OptiMOS 5 process, rated for 30 V VDS, 100 A continuous drain current, and a maximum on-resistance of 2.3 mOhm, packaged in the PG-TDSON-8 (SuperSO8 5x6) surface-mount footprint. It targets high-current synchronous-rectifier and load-switch applications where low conduction loss, low gate charge, and small footprint matter most. A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled semiconductor switch used for power conversion, motor drive, and load management. As an N-channel enhancement-mode device, BSC0502NSIATMA1 turns on when VGS exceeds its gate threshold. The OptiMOS 5 family from Infineon represents the fifth-generation trench MOSFET platform, positioned within the broader hierarchy of discrete semiconductors and power MOSFETs. Key specifications include 2.3 mOhm maximum RDS(on) at VGS = 10 V, a 9.0 nC typical gate charge (0V to 4.5V), and 13.5 nC output charge QOSS. These figures translate directly to low conduction loss at high current, low switching loss in high-frequency converters, and excellent soft-start behavior. The device handles 100 A continuous drain current at TC and 26 A at TA, making it well suited for both thermal-limited and ambient-cooled layouts. The PG-TDSON-8 SuperSO8 package exposes a large source pad that doubles as a thermal pad, giving the part very low thermal resistance from junction to PCB. This allows designers to sink tens of watts of dissipation through copper pours without an external heatsink, simplifying PCB layout. Typical applications include synchronous rectification in 12 V buck converters for server, telecom, and GPU VR rails, hot-swap and OR-ing circuits in redundant power supplies, battery management and protection in e-mobility and power tools, and motor drive in low-voltage brushless DC fans and pumps. The 30 V rating also makes it appropriate for USB-PD sink/source paths and 24 V industrial bus switches. When designing with this part, place gate-drive decoupling within 5 mm of the gate pin and use a 10 kohm gate-source resistor to prevent parasitic turn-on during high dV/dt switching events. Keep the source-sense path tight to avoid Rds_on inflation from package inductance.

It uses an OptiMOS 5 30 V architecture in the surface-mount PG-TDSON-8-6 package. The verified distributor data identifies it as a single N-channel MOSFET designed for high-efficiency power switching. A power MOSFET is a voltage-controlled transistor used to switch or conduct current in power-conversion and motor-control circuits. The N-channel designation means conduction occurs between its drain and source terminals when a positive gate-to-source voltage is applied. Within the hierarchy, the device belongs to the MOSFET family, the broader transistor category, and the power-semiconductor product class. Its low-voltage, high-current construction targets applications requiring compact switching stages and low conduction losses. The verified headline ratings include a 30 V drain-to-source rating, 21 A at Ta, 72 A at Tc, 2.5 W dissipation at Ta, and 30 W at Tc. The package is identified by distributor listings as PG-TDSON-8-6, a surface-mount package with an exposed-pad description in the marketplace record. The part is associated with Infineon’s OptiMOS 5 25 V and 30 V product family, which is aimed at high power density and energy efficiency. BSC0504NSIATMA1 is intended for applications such as synchronous rectification, DC-DC conversion, load switching, and power-management circuits. The 30 V class makes it suitable for low-voltage rails and point-of-load designs where a compact N-channel switch is required. Because the supplied data confirms the package identity and current/power ratings but does not provide a complete datasheet table, parameters such as on-resistance, gate charge, threshold voltage, and thermal resistance require separate datasheet verification. Designers should verify the complete manufacturer datasheet before selecting the part for a particular gate-drive voltage, switching frequency, or thermal layout. The exposed-pad package and the substantial difference between Ta and Tc ratings indicate that PCB copper, thermal vias, and system cooling can strongly affect achievable load current. Current and power values should therefore be interpreted according to the manufacturer’s application conditions rather than as unrestricted universal limits. This page combines verified distributor specifications, official Infineon datasheet access, pricing and stock information, drop-in-comparison guidance, and practical design notes. It is intended to support component identification and preliminary engineering evaluation while clearly separating verified values from parameters that still require datasheet confirmation.
BSC050N03LSGATMA1 - 30V 80A 5mOhm OptiMOS 3 N-FET | Infineon

The combination of ultra-low gate charge, low output charge, and best-in-class RDS(on) in a small footprint makes it the leading choice for high-frequency voltage regulator modules in server, datacom, and telecom power-conversion stages. A power MOSFET is a voltage-controlled switch used to efficiently route or regulate current in switching power supplies, motor drives, and load-management circuits. Within the discrete-semiconductor hierarchy it sits below IGBTs in the family tree of voltage-controlled power switches, and within Infineon's product taxonomy it belongs to the OptiMOS 3 30 V N-channel family, which itself derives from the broader OptiMOS power-management platform. Its primary role is synchronous-rectifier or control-FET duty in DC-DC converter power stages where conduction loss and switching loss must both be minimized. Key electrical characteristics include a 30 V VDS maximum rating, a 5 mOhm maximum RDS(on) at VGS = 10 V, an 80 A continuous drain current at case temperature, a 50 W power dissipation rating at Tc = 25 C, and an optimized gate-charge profile designed for high-frequency buck, synchronous-buck, and OR-ing applications. The SuperSO8 5x6 footprint exposes a substantial source pad that doubles as the primary thermal dissipation path, allowing the die to deliver high current without a separate heatsink. The device uses Infineon's trench MOSFET process technology, which achieves a per-cell on-resistance significantly lower than planar MOSFETs of equivalent die size. The SuperSO8 package pairs a flip-chip-style die attach with a low-inductance lead frame, reducing source inductance and improving switching performance in multi-MHz synchronous-rectifier positions. Typical applications include synchronous-rectifier stages in 12 V-input buck converters for servers and telecom brick modules, high-side and low-side switches in point-of-load regulators, battery-management protection FETs, and OR-ing FETs in redundant power architectures. Its low gate charge and Qgd also suit motor-control and Class-D audio amplifier output stages where switching losses dominate thermal budgets. When designing with this part, pay close attention to the gate-drive voltage. The OptiMOS 3 30 V platform is specified for full enhancement at VGS = 10 V, and a 4.5 V drive is only suitable for low-current applications because RDS(on) rises sharply at reduced gate drive. Use a dedicated gate-driver IC and place the bootstrap or charge-pump supply as close to the gate pin as possible to minimize ringing and unintended shoot-through. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for evaluating BSC050N03LSGATMA1 against its same-family and competitor equivalents in the 30 V N-channel SuperSO8 segment.

Within the broader taxonomy, the BSC050N04LSGATMA1 sits in the OptiMOS 3 family -> trench MOSFET -> power MOSFET -> discrete semiconductor. Key features include an optimized trench-cell geometry with sub-10V gate drive compatibility, avalanche-rated single-pulse energy capability, and a Kelvin-source connection on pin 2 that decouples the gate-drive return path from the high-current source path. The PG-TDSON-8-5 package has a thermal pad that reduces junction-to-board thermal resistance, enabling compact high-current designs without external heatsinks at moderate duty cycles. Technically, the OptiMOS 3 process combines a vertical trench gate with a low-resistance epitaxial drift region, balancing low gate charge (Qg) against low RDS(on) for class-leading figure-of-merit. The part is designed for 12V bus systems such as telecom isolated bus converters, server VRM stages, and OR-ing FET replacement, where it minimizes conduction loss and switching loss simultaneously. Typical applications include synchronous rectification in isolated DC-DC brick converters, secondary-side high-current OR-ing, point-of-load (POL) buck regulators, hot-swap controllers on 36V-40V distribution rails, and Class-D audio amplifier output stages. The 40V rating also provides ample margin for 24V industrial battery systems. When designing with this part, ensure the gate driver can source and sink at least 2A peak to charge the gate capacitance in under 50ns. Use a Kelvin-source connection whenever possible to keep the gate-drive loop decoupled from the high-current source path and avoid shoot-through in synchronous-rectifier bridges.

It delivers a maximum on-resistance of 5 mOhm and dissipates up to 28W at 25°C case temperature, with a typical R_DS(on) of 4.2 mOhm at V_GS=10V. An N-channel power MOSFET is a voltage-controlled semiconductor switch in which the channel is formed by electrons (rather than holes), enabling lower on-resistance per unit silicon area than equivalent P-channel devices. Power MOSFETs sit in the device hierarchy: transistor -> FET -> MOSFET -> power MOSFET -> N-channel power MOSFET, and they are widely used as the low-side or high-side switch in synchronous buck converters, motor drivers, and load-switch circuits where fast switching and low conduction loss are required.

The 8-pin TDSON package includes an exposed drain pad for direct PCB thermal dissipation. Architecturally, the device uses a stripe-trench cell design with a very thin gate oxide, giving sub-5 mOhm on-resistance at 10V V_GS while maintaining safe operating area (SOA) for hot-plug and inrush events. Avalanche-rated energy (E_AS) per the manufacturer datasheet supports rugged operation in inductive switching. Typical applications include synchronous buck DC-DC converters for server and telecom point-of-load, USB-PD power-path OR-ing, hot-swap circuits in 12V distributed-power systems, battery protection and load switching in power tools, and high-current motor drive half-bridges in industrial automation. Design tip: keep the gate-drive loop (gate resistor + gate-drive IC output to gate/source) physically tight to minimize parasitic inductance that can ring above V_GS(max) = ±20V during fast switching transitions. Add a 10kohm gate-source pull-down if the gate may float during controller start-up.

The OptiMOS 5 cell architecture delivers lower Qg, Qgd, and Qrr figures than its predecessor, enabling faster switching edges and higher efficiency at elevated switching frequencies. The device uses Infineon's advanced trench-gate process with an optimized body diode that minimizes reverse-recovery charge (Qrr). This makes it ideal for the synchronous-rectifier (SR) position in half-bridge and full-bridge topologies, where the body diode otherwise dominates switching loss and can cause shoot-through during dead time. Typical applications include synchronous rectification in 48 V telecom and server point-of-load converters, primary-side switching in telecom DC-DC bricks, motor drive H-bridges, and high-current OR-ing / hot-swap circuits. It is particularly suited for high-switching-frequency (>300 kHz) hard-switched and soft-switched converters where conduction and switching losses must both be minimized. When designing with this device, ensure the gate-driver can source/sink sufficient peak current to charge the gate charge within the desired switching period, and pay attention to PCB layout to minimize source-inductance loop area, which is critical for limiting voltage overshoot and ringing at the drain node.

The part is qualified to JEDEC MSL1 standards and is RoHS compliant with lead-free reflow compatibility. The OptiMOS 3 architecture uses an advanced trench cell design that minimizes the RDS(on) x Qg figure of merit, balancing conduction and switching losses. The SuperSO8 package uses wire-bond-free source-down technology on later revisions, but the BSC054N04NSGATMA1 uses standard bond-wire construction with a gull-wing lead frame.

Typical applications include synchronous rectification in 12V buck converters for server and telecom point-of-load (POL) regulators, OR-ing and hot-swap circuits in 24V industrial bus systems, motor drive H-bridges for low-voltage brushed and brushless DC motors, and battery protection circuits in multi-cell Li-ion packs. The 40V rating provides ample margin above 19V max USB-PD voltages and 24V industrial rails. When designing with this MOSFET, prioritize minimizing parasitic source-inductance by using short, wide copper pours on the source pads, and ensure the gate-drive voltage reaches at least 10V for full enhancement. A heatsink or substantial copper thermal pad area is required for continuous operation near the 81A pulsed rating.

The OptiMOS 6 technology delivers improved Figure of Merit (FOM = RDS(on) x Qg) versus prior generations, enabling higher power density in switched-mode power supplies. The OptiMOS 6 40V power MOSFET family is optimized for synchronous rectification in switched mode power supplies (SMPS) in servers, desktops, and telecom bricks, as well as for DC-DC converters, battery management systems (BMS), motor drives, and OR-ing functions. The SuperSO8 package provides an exposed pad that lowers thermal resistance to the PCB copper pour, supporting 38 W dissipation at 25C case temperature with proper board layout. Compared to the earlier OptiMOS 5 generation, OptiMOS 6 reduces switching losses by approximately 20% through optimized gate charge (Qg) and output capacitance (Coss) characteristics, while maintaining the same 40 V voltage class. This makes the part particularly attractive for high-frequency (>300 kHz) buck and synchronous rectification stages where switching loss dominates total power dissipation. Typical applications include synchronous rectification in server and telecom SMPS, 12 V and 24 V DC-DC point-of-load converters, hot-swap and OR-ing controllers, battery protection and load switching in BMS, and low-voltage motor drive half-bridges. The 5.9 mOhm RDS(on) minimizes conduction loss in high-current 12 V rails. When designing with this device, keep the gate-source voltage below the 20 V VGS(max) rating and provide adequate copper pour (typically 1 in2 minimum) to keep thermal resistance within budget. Use a gate driver with sufficient source/sink current (typically >1 A peak) to fully exploit the switching speed advantage of OptiMOS 6.
BSC059N04LSGATMA1 - 40V 73A 5.9mOhm N-Ch OptiMOS 3 | Infineon
The Infineon BSC059N04LSGATMA1 is an N-channel power MOSFET rated at 40 V drain-source voltage and 73 A continuous drain current (Tc), built on Infineon's OptiMOS 3 technology and housed in a SuperSO8 5x6 (PG-TDSON-8-5) surface-mount package. The part delivers a maximum on-state resistance of 5.9 mOhm at VGS=10 V and supports up to 50 W of power dissipation at 25 C case temperature, with a typical RthJC well below 2 C/W enabling very compact synchronous-rectifier and OR-ing designs. An N-channel power MOSFET is a voltage-controlled three-terminal device in which the gate-source electric field modulates a conducting channel between drain and source. Power MOSFETs are the fundamental switching element in modern switched-mode power supplies, motor drives, and battery protection circuits. They occupy a place in the broader hierarchy of discrete semiconductors -> transistors -> field-effect transistors -> power MOSFETs, and are increasingly being challenged by GaN HEMTs and SiC MOSFETs in very high-voltage or very high-frequency applications, but at sub-100 V rails silicon MOSFETs still dominate on cost and ruggedness. The headline figure is the ultra-low 5.9 mOhm maximum RDS(on) at 10 V VGS, achieved in a small 5x6 mm footprint. The device also features low gate charge (Qg typically around 25 nC for this family), a logic-level-compatible 4.5 V VGS(th) range, and is qualified to MSL1 (JEDEC J-STD-020) and RoHS/REACH compliance standards. The SuperSO8 package provides a low-thermal-resistance path and source-down bottom metal for direct PCB heat-sinking, which is critical when the FET is used as a low-side synchronous rectifier. OptiMOS 3 uses a trench-gate vertical DMOS cell structure optimised for low figure-of-merit (FOM = RDS(on) x Qg), reducing both conduction and switching losses compared to planar MOSFET generations of equivalent on-resistance. The 40 V rating gives substantial margin above nominal 12 V and 24 V bus voltages, and the 73 A continuous current makes the part suitable for high-current point-of-load converters and active battery balancing stages. Avalanche-rated single-pulse energy further increases robustness under inductive switching. Typical applications include synchronous rectification in 12 V buck and buck-boost converters for servers, telecom and datacom equipment, battery management and protection in e-mobility tools and e-bikes, OR-ing FETs in redundant power architectures, and low-side switches in motor-control and solenoid drivers. Designers often pair this part with a half-bridge gate driver such as the 2EDN7534 family on the control side. When designing with this part, pay close attention to gate-drive voltage: at VGS below 8-9 V the RDS(on) rises sharply and conduction loss grows. For very low-duty, low-loss applications consider the VGS=10 V guaranteed RDS(on) figure rather than typical. Layout must use wide copper pours under the source pad for thermal spreading and short Kelvin-source connection if available. This page synthesises distributor pricing as of 2026-09-14, verified drop-in alternatives drawn from the same Infineon OptiMOS 3 family, and practical design notes that supplement the manufacturer datasheet.
BSC060N10NS3GATMA1 - 100V 6mOhm OptiMOS 3 N-FET | Infineon
The Infineon BSC060N10NS3GATMA1 is an N-channel power MOSFET built on Infineon's OptiMOS 3 platform, rated at 100 V VDSmax with a typical on-resistance of 6 mOhm and continuous drain current of 14.9 A (Ta) / 90 A (Tc), housed in a PG-TDSON-8-1 (SuperSO8 5x6) surface-mount package. Per the manufacturer datasheet, this part delivers a 30 percent reduction in both RDS(on) and figure-of-merit compared to the previous OptiMOS generation, making it well suited to high-power-density switched-mode power supplies. A power MOSFET is a voltage-controlled three-terminal semiconductor device that uses an electric field at the gate to control current flow between the drain and source terminals. Within the discrete-semiconductor hierarchy, a power MOSFET belongs to the family of field-effect transistors -> transistors -> discrete semiconductors, and within Infineon's portfolio OptiMOS 3 sits in the high-performance low-voltage tier (40 V to 300 V) used in telecom, server, and consumer SMPS applications. The BSC060N10NS3 is optimized as a synchronous-rectifier or low-side switch where minimal conduction loss matters most than the fastest switching speed. Key specifications include 100 V drain-source breakdown voltage, 6 mOhm maximum RDS(on) at VGS = 10 V, 125 W power dissipation at Tc = 25 C, gate threshold VGS(th) of 2.0 V to 3.5 V, and an operating junction range of -55 C to +150 C. The PG-TDSON-8-1 (also called SuperSO8) footprint is a thermally-enhanced 5 mm x 6 mm DFN-style package with an exposed drain pad that doubles as the main heat-dissipation path. Typical applications include synchronous rectification in 48 V telecom bus converters, primary-side switching in telecom and server SMPS, motor-drive H-bridges, DC-DC buck and synchronous buck stages, and battery management protection in e-mobility and e-bike systems. The combination of low RDS(on) and small package footprint also makes it a strong fit for solar micro-inverters and industrial point-of-load regulators where board area and conduction loss dominate the thermal budget. When designing with this device, ensure the gate drive swings cleanly to 10 V for full enhancement and add a gate-source resistor (typically 10 kOhm to 100 kOhm) to prevent floating-gate turn-on. The exposed pad must be soldered to a sufficiently large copper pour (at least 1 square cm on each side of the board) to keep junction temperature within safe limits; the datasheet SOA curve shows the part can sustain roughly 50 A continuously at 25 C case temperature.
BSC060P03NS3EGATMA1 - 30V P-Ch MOSFET 6mΩ 100A OptiMOS | Infineon
The Infineon BSC060P03NS3EGATMA1 is a P-channel power MOSFET from the OptiMOS™ family rated at 30V VDS, with a maximum on-state resistance of 6 mΩ at VGS=10V and continuous drain current of 17.7A (Ta) up to 100A (Tc), housed in a SuperSO8 5x6 (PG-TDSON-8-1) surface-mount package. What is a P-channel power MOSFET? A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled semiconductor switch used to route or modulate current. A P-channel variant conducts when the gate is pulled below the source potential, which makes it ideal for high-side load switching where a low-side N-channel switch would require an extra bootstrap or charge-pump circuit. Within the broader taxonomy, this part belongs to: power MOSFET -> discrete semiconductor -> power management building block. OptiMOS™ is Infineon's trench-process technology platform, and the P-channel OptiMOS family targets applications needing the simplest possible gate-drive topology. Key specifications include a maximum gate threshold of 2.5V (typ), ultra-low RDS(on) of 6 mΩ at VGS=10V, total gate charge of 81 nC at VGS=10V, and a maximum power dissipation of 83W (Tc). The integrated exposed pad (SuperSO8) provides a thermal resistance on the order of low single-digit C/W with proper PCB copper area, supporting sustained high-current operation in space-constrained designs. The device uses Infineon's advanced trench technology to achieve a best-in-class figure-of-merit (FOM = RDS(on) × Qg), minimizing both conduction and switching losses. The P-channel polarity allows direct interfacing with low-voltage microcontroller GPIO outputs without a charge pump, simplifying high-side load-switch designs and reducing BOM count. Typical applications include load switching in 12V automotive and industrial rails, battery protection and OR-ing, DC-DC converters (especially as the high-side synchronous rectifier or control FET), USB power switches, motor drive H-bridges, and hot-swap controllers. The 30V rating provides ample margin for 12V bus transients. When designing with this MOSFET, pay attention to gate-drive strength: a 10V gate is required for the lowest RDS(on), but the part still turns on at ~-2.5V VGS(th) making it directly drivable from 3.3V or 5V logic via a small pull-up to source. Ensure the exposed pad has sufficient copper to dissipate the 83W maximum rating safely under realistic mounting conditions.

BSC066N06NSATMA1 - 60V N-Ch MOSFET 6.6mΩ OptiMOS | Infineon
The Infineon BSC066N06NSATMA1 is an N-channel 60 V OptiMOS power MOSFET housed in a PG-TDSON-8-6 (TDSON EP) surface-mount package, rated for 64 A continuous drain current at 25°C case temperature with a maximum on-resistance of 6.6 mΩ at VGS=10 V. It is designed for high-efficiency DC-DC conversion and synchronous rectification in telecom, server, and automotive-grade power systems. An N-channel power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled three-terminal device (Gate, Drain, Source) that conducts current when a positive gate-to-source voltage exceeds the threshold. Power MOSFETs sit within the broader category of discrete semiconductors -> transistors -> MOSFETs -> power MOSFETs, and are the workhorse switching element in modern switched-mode power supplies (SMPS), motor drives, and battery protection circuits because they switch faster and dissipate less energy than bipolar transistors or relays. Key features include an ultra-low RDS(on) of 6.6 mΩ at VGS=10 V, a logic-level compatible gate threshold (typ. 1.7 V, fully enhanced at 4.5 V), and a repetitive avalanche-rated body diode. The PG-TDSON-8-6 package exposes the drain pad for direct thermal coupling to a top-side copper pour, achieving a junction-to-case thermal resistance of 1.3 °C/W and supporting 46 W continuous dissipation at Tc=25°C. The device is built on Infineon's OptiMOS 5 60 V process, which uses a trench-gate cell architecture combined with a low-resistance substrate. This yields both lower RDS(on) per unit area and superior switching FOM (RDS(on) × Qg) compared with planar MOSFETs of equivalent die size, making it suitable for high-frequency buck/boost converters where switching losses dominate. Typical applications include synchronous rectification in 48 V telecom and server intermediate bus converters, high-current DC-DC point-of-load regulators, eBike and power tool motor drives, and battery management system (BMS) charge/discharge switches. The wide SOA also supports hot-swap and OR-ing functions in redundant power architectures. When designing with this part, prioritize a top-side thermal copper pour tied to the exposed drain pad, and minimize the gate-drive loop inductance to prevent ringing above VGS(max)=±20 V. The device's logic-level threshold allows direct drive from 5 V PWM controllers, but a dedicated gate driver is recommended above 50 kHz switching frequency to achieve clean edges and minimize switching loss.

BSC070N10NS5ATMA1 - 100V 7mOhm OptiMOS 5 N-MOSFET | Infineon
The Infineon BSC070N10NS5ATMA1 is an N-channel power MOSFET built on Infineon's OptiMOS 5 100V technology, rated at 100V VDS max, 7 mOhm RDS(on) max, and 80A continuous drain current (Tc) in a SuperSO8 5x6 (PG-TDSON-8-7) surface-mount package. It is optimized for synchronous rectification in switched-mode power supplies, delivering up to 44% output capacitance reduction and up to 43% RDS(on) reduction versus the previous generation, which translates directly into lower switching and conduction losses and higher power density per square centimeter of board area. A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled three-terminal switching device that uses an insulated gate to modulate conduction between source and drain. Within the broader power-converter hierarchy, a MOSFET sits at the switching element of a buck, boost, or half-bridge converter, downstream of the PWM controller and upstream of the output inductor and capacitor; it belongs to the wider family of power discretes (MOSFETs, IGBTs), which are themselves a sub-category of discrete semiconductors used in power management applications. OptiMOS 5 is Infineon's fifth-generation 100V trench MOSFET platform, distinguished by a lower figure of merit (RDS(on) x Qg) than prior generations. Key differentiating specifications include a typical gate charge in the single-digit nC range for fast switching edges, a low Qrr body-diode reverse-recovery charge that suits continuous-conduction-mode (CCM) hard switching, and a PG-TDSON-8-7 package with an exposed thermal pad that keeps junction-to-case thermal resistance RthJC in the sub-1 C/W range - enabling 83W (Tc) power dissipation per the Infineon datasheet. The part is rated 2.5W at TA=25C without additional heatsinking, but PCB copper pours or an external heatsink are required at higher ambient temperatures. Typical applications include 48V telecom and server bus converters, synchronous rectification in isolated DC-DC bricks, motor-drive H-bridges for industrial fans and e-bikes, hot-swap and OR-ing controllers in 12V/24V/48V distribution, and high-frequency point-of-load (POL) converters for compute platforms. The OptiMOS 5 family is also widely used in solar micro-inverters and battery-management protection FETs where both low RDS(on) and small Qgd are simultaneously required. When designing with this device, select a gate driver capable of 4V to 10V VGS with sub-50ns propagation delay to exploit the part's fast switching capability. Place the gate-drive loop area to a minimum and use 1-2 ohms of external gate resistance to control dV/dt-induced ringing, and verify SOA at the intended switching frequency using the manufacturer's safe-operating-area curves rather than relying on pulsed thermal limits alone.
BSC072N08NS5ATMA1 - 80V 74A N-Channel OptiMOS 5 MOSFET | Infineon
The Infineon BSC072N08NS5ATMA1 is an 80 V N-channel power MOSFET rated for 74 A continuous drain current, featuring a maximum on-resistance of 7.2 mOhm, housed in a SuperSO8 / PG-TDSON-8-7 surface-mount package and built on Infineon's OptiMOS 5 technology platform. The part is offered in a tape-and-reel ATMA1 shipping pack and is qualified for industrial and consumer power conversion. What is an N-channel power MOSFET? A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled semiconductor switch used to route and regulate current in electronic circuits. N-channel MOSFETs conduct between drain and source when a positive gate-source voltage is applied, offering low on-resistance per unit silicon area. Power MOSFETs form a sub-category of discrete semiconductors within the power management hierarchy, sitting alongside IGBTs, voltage regulators, and DC-DC converters, and they are typically used as synchronous rectifier or low-side switching elements in switched-mode power supplies (SMPS), motor drives, and battery management circuits. Key features of the BSC072N08NS5ATMA1 include a maximum drain-source voltage (VDS) of 80 V, continuous drain current of 74 A at case (Tc), pulsed current handling suited to inductive loads, an ultra-low typical on-resistance (RDS(on)) of 7.2 mOhm at VGS = 10 V, and an industry-standard SuperSO8 5x6 mm footprint. The OptiMOS 5 process trades lower gate charge and lower figure of merit (FOM) for the same RDS(on), directly reducing switching and conduction losses in 48 V and 24 V bus applications. Architecturally, OptiMOS 5 uses an advanced trench cell structure with optimized charge balance, achieving a low RDS(on)*Qg figure of merit versus earlier generations. The SuperSO8 package provides a low thermal resistance path through the exposed pad, supporting high continuous current without external heatsinking at moderate duty cycles. Typical applications for BSC072N08NS5ATMA1 include synchronous rectification in 48 V telecom and server bus converters, high-current buck or buck-boost converters in industrial point-of-load regulation, battery management and protection in 12 V/24 V Li-ion packs, brushless DC motor drive half-bridges, and solar micro-inverter low-side switches. The 80 V rating provides comfortable headroom for 24 V industrial and 36 V/48 V nominal bus rails. When designing with this MOSFET, ensure the gate driver can source and sink enough current to charge Qg within the desired switching period, and provide a low-impedance Kelvin source connection (the SuperSO8 pinout supports this) to keep gate-loop inductance low and avoid ringing. A heatsink or substantial copper pour is required for continuous high-current operation above 3-5 W dissipation. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including a side-by-side comparison against same-family Infineon OptiMOS 5 parts and competing N-channel MOSFETs in the same PG-TDSON-8-7 footprint.
BSC074N15NS5ATMA1 - 150V 7.4mΩ OptiMOS 5 N-MOSFET | Infineon
The Infineon BSC074N15NS5ATMA1 is a 150V N-channel power MOSFET built on Infineon's OptiMOS™ 5 trench technology, delivering a maximum drain-source on-resistance of 7.4 mΩ and a continuous drain current of 114 A at 25°C case temperature, packaged in a SuperSO8 5x6 (PG-TSON-8-3) outline with wettable flanks for automated optical inspection. A power MOSFET is a voltage-controlled switch that uses an insulated gate to modulate current flow between drain and source terminals; N-channel MOSFETs are the dominant switching device in modern synchronous buck converters, motor drives, and hot-swap controllers because their lower on-resistance per unit silicon area outperforms equivalent P-channel parts. The OptiMOS 5 family specifically targets 100V–300V applications where figure-of-merit (FOM = RDS(on) × Qg) reductions translate directly into lower switching losses and higher power density. Key features include a 7.4 mΩ maximum RDS(on) at VGS = 10V, 150V drain-source breakdown voltage, low gate charge for high-frequency switching, and an integrated wettable-flank package that simplifies solder joint inspection. The SuperSO8 5x6 footprint occupies roughly 30 mm² and exposes the drain tab for direct PCB heatsinking, eliminating the need for an isolated thermal interface. The OptiMOS 5 cell architecture combines a charge-balanced superjunction-style body region with a refined trench gate, achieving the lowest RDS(on)·Qg figure-of-merit in its voltage class. The part also integrates a robust body diode suitable for hard-switched bridge topologies, reducing reliance on external anti-parallel diodes in half-bridge and full-bridge configurations. Typical applications include telecom 48V hot-swap controllers, synchronous rectification in isolated DC-DC converters, Class-D audio amplifier output stages, and industrial motor drive half-bridges. Its 150V rating provides comfortable margin for 48V nominal telecom rails and 100V battery systems. When designing with this part, ensure gate-drive voltage reaches at least 10V for full enhancement, and place the gate-source resistor (typically 10–100 kΩ) close to the device to prevent inadvertent turn-on from Miller coupling during fast switching transitions. This page synthesizes Infineon OptiMOS 5 datasheet values, distributor pricing snapshots, and curated drop-in alternatives so procurement and design engineers can evaluate the BSC074N15NS5ATMA1 against pin-compatible 150V N-channel MOSFETs in a single, citation-ready view.
BSC076N04NDATMA1 - 40V 20A 7.6mOhm Dual N-MOSFET | Infineon
The Infineon BSC076N04NDATMA1 is a 40V dual N-channel MOSFET array built on Infineon's OptiMOS™ 3 trench technology, delivering 20A continuous drain current per channel with a maximum on-resistance of 7.6 mOhm at VGS=10V, housed in a SuperSO8 (PG-TDSON-8-4) 5x6 mm surface-mount package. It is qualified for high operating junction temperatures up to 175 C and offers superior thermal resistance for high power density designs in the smallest footprint. An N-channel MOSFET is a voltage-controlled four-terminal semiconductor switch (gate, drain, source, body) that conducts current when a positive gate-to-source voltage exceeds the threshold voltage (about 4V for this part). The BSC076N04NDATMA1 integrates two independent N-FETs in one package - the array belongs to the metal-oxide-semiconductor field-effect transistor (MOSFET) family, under discrete semiconductors in the power MOSFET hierarchy (MOSFET -> power transistor -> discrete semiconductor -> semiconductor). This architecture is widely used for synchronous rectification, half-bridges, and ORing circuits where two switches share one footprint. Key features include the OptiMOS™ 3 trench cell design that minimizes RDS(on) x gate charge (Qg) figure of merit, high shot-through immunity due to Qgd/Qgs ratio below 0.8 (reducing cross-conduction risk in half-bridge topologies), Pb-free plating, and RoHS compliance. The dual SuperSO8 package achieves substantially better thermal resistance than competing dual DFN packages while occupying only 5x6 mm of board area. Maximum power dissipation is 2.3W at TA=25 C and 65W at TC=25 C. The device uses a vertical trench MOSFET structure with N+ source and N- epitaxtial drift region; the low on-resistance is enabled by high cell density. OptiMOS™ 3 also reduces reverse-recovery charge (Qrr) of the intrinsic body diode, improving hard-switched efficiency. Typical applications include DC-DC converter synchronous buck stages, motor drive half-bridges, eFuse / hot-swap circuits, battery management ORing FETs, and Class-D audio amplifier outputs. The low RDS(on) minimizes conduction loss, while the 40V rating provides ample margin for 12V bus rails with transients. When designing, ensure VGS drive reaches at least 10V for full RDS(on) specification and keep gate-loop inductance low to suppress ringing. A 4V-7V gate-source absolute maximum should be respected if driven from logic-level signals. This page synthesizes distributor pricing, verified cross-reference alternatives, and practical PCB layout notes not found in the manufacturer datasheet, making it a one-stop engineering reference for BSC076N04NDATMA1 selection and qualification.
BSC076N06NS3GATMA1 - 60V 50A 7.6mΩ OptiMOS 3 N-MOSFET | Infineon
The Infineon BSC076N06NS3GATMA1 is an N-channel power MOSFET built on Infineon's OptiMOS 3 technology, rated for 60 V VDS and continuous drain current of 50 A at TC, packaged in a surface-mount PG-TDSON-8-5 (SuperSO8 5x6). It delivers an extremely low maximum on-resistance of 7.6 mΩ at VGS=10 V and 10.4 mΩ at VGS=4.5 V, making it one of the most efficient 60 V trench MOSFETs in this footprint. Power dissipation is 2.5 W on a 1 in² FR4 board at TA=25°C and 69 W with the case held at TC=25°C. A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled switch that uses an insulated gate to modulate current flow between source and drain terminals. The "N-channel" designation means conduction electrons form the channel, giving lower on-resistance per unit area than equivalent P-channel parts. In the broader taxonomy, MOSFETs sit under discrete semiconductors -> transistors -> field-effect transistors -> power switches. Low-RDS(on) OptiMOS devices sit at the high-efficiency end of this hierarchy. Key features of the BSC076N06NS3 include a logic-compatible 4.5 V drive threshold, low gate charge for high-frequency switching, and an optimized body diode that supports synchronous rectification topologies. The SuperSO8/PG-TDSON-8-5 footprint provides top-side cooling via the exposed pad, achieving a junction-to-case thermal resistance of approximately 1.8 K/W. The part is RoHS compliant and uses halogen-free molding compound. OptiMOS 3 uses Infineon's trench-gate process to shrink cell pitch and reduce both RDS(on) and gate charge simultaneously. The result is a figure-of-merit (FOM = RDS(on) × Qg) that is well below older planar 60 V generations, directly translating into lower conduction and switching losses in SMPS, motor drive, and ORing applications. The gate-oxide is rated for ±20 V VGS transients. Typical applications for this part include synchronous rectification in 48 V telecom and server DC-DC converters, hot-swap and ORing controllers in distributed power systems, high-current DC motor drives in industrial automation, and battery protection in 12 V/24 V e-mobility platforms. The combination of 50 A continuous current and 7.6 mΩ RDS(on) makes it ideal where both efficiency and thermal headroom are critical. Designers should pay close attention to gate-drive design: the 4.5 V VGS rating requires a true 10 V gate-drive rail for full enhancement, while 4.5 V operation works at the cost of higher RDS(on). PCB layout must minimize source-inductance loop area to limit voltage overshoot on the drain during switching transients above 50 A. This page synthesizes distributor pricing, parametric drop-in alternatives, and practical PCB layout notes not found in the Infineon datasheet - information designed for engineers selecting MOSFETs for power-conversion and motor-drive designs.
BSC077N12NS3GATMA1 - 120V OptiMOS 3 N-Ch MOSFET, 7.7mΩ | Infineon
The Infineon BSC077N12NS3GATMA1 is an N-channel power MOSFET from the 120 V OptiMOS 3 family, offering the industry's lowest on-state resistance (7.7 mΩ max) combined with the fastest switching behavior in a compact PG-TDSON-8-1 (SuperSO8 5x6) surface-mount package. The device is rated at 120 V VDS and delivers continuous drain current of 13.4 A at Ta (or 98 A at Tc), with a total power dissipation of 139 W at Tc. An OptiMOS power MOSFET is a trench-technology N-channel enhancement-mode device designed to minimize conduction and switching losses in power conversion stages, sitting in the hierarchy: trench MOSFET -> power MOSFET -> discrete semiconductor -> power management. The OptiMOS 3 120 V family balances ultra-low RDS(on) with low gate charge and excellent body-diode ruggedness, enabling high-frequency, high-efficiency designs. Key features include an industry-leading 7.7 mΩ maximum RDS(on) at VGS = 10 V, an excellent figure of merit (FOM = RDS(on) × Qg), and a 120 V drain-source breakdown voltage that provides substantial headroom over nominal 48 V or 72 V bus rails. The SuperSO8 5x6 package (PG-TDSON-8-1) provides a thermal resistance around 1.0 C/W (RthJC), supporting high-current operation with proper PCB thermal design. Technically, the device uses Infineon's third-generation OptiMOS trench process, which optimizes cell pitch and epitaxial structure to reduce both on-resistance and switching losses simultaneously. This makes it well suited for synchronous rectification, DC-DC conversion, motor drive, and hot-swap stages where high efficiency and small PCB footprint are mandatory. Typical applications include synchronous rectification in telecom and server SMPS, 48 V eMobility and mild-hybrid auxiliary converters, DC-DC buck/boost converters for industrial and computing systems, motor control and Class-D audio amplifiers, and hot-swap / OR-ing circuits on 48 V rails. The wide 120 V rating also makes it suitable for solar and battery management. A key design consideration is gate-drive voltage: the device is fully enhanced at VGS = 10 V, with a typical gate threshold of 2.5 V, so a 10 V driver is required to reach the published on-resistance. A small external gate resistor (4.7-10 Ω) controls ringing and EMI. The exposed pad must be soldered to a large copper pour for thermal performance. This page synthesizes distributor pricing, drop-in alternative cross-references, and practical design notes not found in the manufacturer datasheet alone, giving engineers a complete decision matrix for selecting or replacing the BSC077N12NS3GATMA1.
BSC084P03NS3GATMA1 - P-Ch 30V 78.6A OptiMOS P3 MOSFET | Infineon
The Infineon BSC084P03NS3GATMA1 is a P-channel power MOSFET built on Infineon's OptiMOS P3 platform, rated for -30 V VDS and continuous drain current up to 14.9 A (Ta) or 78.6 A (Tc) in a surface-mount PG-TDSON-8-5 package. Its headline figures are 6.1 mOhm Rds(on) at VGS = -10 V and 58 nC total gate charge, giving very low conduction and switching losses for 30 V-class load-switch and synchronous-rectifier applications. A P-channel power MOSFET is a voltage-controlled unipolar device in which the drain current flows when a negative gate-to-source voltage is applied. The P-channel variant is the polarity complement of an N-channel MOSFET; it is particularly useful in load-switch and high-side reverse-battery-protection circuits because it can be driven with the same ground-referenced logic that controls the upstream N-channel regulator, eliminating the need for a charge pump or bootstrap supply. Within the broader hierarchy, a P-channel MOSFET sits below discrete transistors, above power-management switch ICs, and inside the wider MOSFET > transistor > discrete semiconductor taxonomy. The OptiMOS P3 technology combines a trench-gate structure with optimized cell pitch to deliver the lowest Rds(on) per unit area in this voltage class. Key differentiators include 6.1 mOhm Rds(on) at -10 V VGS, an industry-leading figure-of-merit (FOM = Rds(on) x Qg), 110 pF Coss for low switching loss, and 1.52 nF Crss for good dv/dt immunity. The 69 W power dissipation rating (Tc) allows sustained high-current operation when the die is properly heatsinked via the exposed pad. Typical applications include load-switch management in notebook and tablet motherboards, high-side reverse-polarity protection in 12 V/24 V industrial systems, battery protection and OR-ing in Li-ion battery packs, synchronous rectification in buck converters, and motor-drive H-bridges where low-side switching requires a complementary P-channel device. The TDSON-8-5 footprint with exposed thermal pad is widely adopted in power-dense designs. When designing with this device, ensure that the gate drive swing reaches at least -10 V to achieve the datasheet Rds(on). Place a gate-to-source resistor (typically 10 kOhm to 100 kOhm) close to the IC pins to prevent floating-gate turn-on, and use the exposed pad as the primary thermal path with multiple thermal vias to inner copper planes.
BSC0901NSATMA1 - 30V 100A OptiMOS N-Channel MOSFET | Infineon
The Infineon BSC0901NSATMA1 is an N-channel power MOSFET from the OptiMOS 30V family, rated at 30V VDS, 100A continuous drain current at Tc, and housed in a SuperSO8 / TDSON-8-5 (PG-TDSON-8-5) surface-mount package. Per the manufacturer datasheet, the part delivers an ultra-low typical on-state resistance of approximately 1.5 mOhm at 10V VGS, with a maximum rated RDS(on) of 1.9 mOhm, making it one of the lowest-resistance 30V parts in this footprint class. The 5x6 mm exposed-pad package supports 2.5W power dissipation at Ta and 69W at Tc. A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled semiconductor switch used to efficiently route or regulate current in power conversion circuits. Within the broader taxonomy, the BSC0901NSATMA1 belongs to the N-channel enhancement-mode MOSFET family, which itself is a sub-type of discrete power transistors used in switching power supplies, motor drives, and synchronous rectification. OptiMOS is Infineon's family of trench-gate power MOSFETs optimized for low RDS(on), low gate charge (Qg), and high switching frequencies, which together reduce both conduction and switching losses. Key differentiating specifications of the BSC0901NSATMA1 include its 30V drain-to-source breakdown voltage, 100A continuous drain current rating at the case, and ultra-low gate charge and output charge figures (typical Qg in the tens of nC range). The combination of low Qg and low RDS(on) yields an excellent FOM (Figure of Merit, RDS(on) x Qg), directly translating into higher efficiency in switched-mode power supplies. The part is rated for avalanche energy (EAS) of 80 mJ per the Vyrian listing and supports a moisture sensitivity level of 1. Technically, the BSC0901NSATMA1 is built on Infineon's advanced OptiMOS trench technology, which uses a shielded-gate structure to reduce on-resistance without compromising switching speed. The TDSON-8-5 package provides a low-inductance source connection (pin 2, 3 and exposed pad) and an internal Schottky-like body diode optimized for synchronous rectification. The result is a part suitable for hard-switching topologies at high frequencies with minimal ringing and reduced reverse-recovery losses. Typical applications for the BSC0901NSATMA1 include voltage regulator solutions (VRs) for servers, datacom and telecom, point-of-load (POL) converters, synchronous buck stages, hot-swap circuits, and battery protection / ORing in 12V distributed power architectures. The wide safety margin in VDS also makes it appropriate for motor drive and power tool applications. When designing with this part, ensure the gate drive voltage is at least 10V for full enhancement into the low-RDS(on) region. Use Kelvin-source (pin 2) connection on the gate driver return path to suppress source-inductance induced ringing, and place the gate driver within 5 mm of the gate pad to limit parasitic loop inductance.
