The Infineon BSC0901NSIATMA1 is an N-Channel 30 V OptiMOS power MOSFET rated for 28 A continuous drain current at 25 C ambient (100 A pulsed at case temperature) housed in a compact surface-mount PG-TDSON-8-6 package. The device delivers ultra-low on-state resistance of approximately 2 mOhm at 10 V VGS combined with low gate charge, making it well suited to high-current DC-DC conversion in server, datacom, and telecom rails. Continuous drain power dissipation is rated 2.5 W at 25 C ambient and 69 W with case-temperature-controlled mounting, giving designers flexible thermal headroom depending on PCB copper area. A power MOSFET is a voltage-controlled switching device that uses an insulated gate to modulate current flow between drain and source terminals. Within the broader semiconductor taxonomy, MOSFETs belong to the discrete power transistor family alongside IGBTs and BJTs, and OptiMOS 25V specifically targets low-voltage, high-current synchronous rectification and hot-swap applications. The PG-TDSON-8-6 package family is a member of the SON/QFN-style surface-mount family, with a large exposed thermal pad enabling low junction-to-case thermal resistance for compact high-power-density designs. Key features include 30 V drain-source breakdown, 100 A pulsed drain current at Tc, 2 mOhm max R_DS(on) at 10 V VGS, 2.2 V maximum threshold voltage, and an integrated gate-source ESD protection structure. The OptiMOS 25V technology provides a figure-of-merit that combines low switching losses with low conduction losses - critical for MHz-class switching converters. The TDSON-8 footprint has a 5x6 mm body with an exposed drain pad that doubles as the thermal dissipation surface. Typical applications include server voltage regulator modules (VRMs), synchronous buck converters in datacom/telecom point-of-load regulators, hot-swap controllers, and battery protection in 12 V Li-ion packs. The 30 V rating also covers 24 V industrial bus rails with adequate transient headroom. When designing with this device, minimize high-frequency gate-loop inductance by keeping the gate drive return path directly over the source pad. A 10 V gate drive is recommended to fully enhance the channel; using 4.5 V gate drive increases R_DS(on) by roughly 2x. Always verify SOA against your actual switching profile and PCB thermal performance - the data above summarizes a design survey, not a substitute for a full bench characterization.

The Infineon BSC094N06LS5ATMA1 is an N-channel power MOSFET built on Infineon's OptiMOS™ 5 logic-level technology, rated for 60 V VDS, 9.4 mΩ maximum RDS(on), and 47 A continuous drain current at TC, in a SuperSO8 5x6 (PG-TDSON-8-6) surface-mount package. It is supplied on a 13-inch tape-and-reel carrier (ATMA1 suffix) and is qualified to -55 °C to +150 °C junction-temperature operation. A power MOSFET is a voltage-controlled semiconductor switch that uses an insulated gate to modulate current flow between source and drain terminals. The OptiMOS™ 5 family is Infineon's fifth-generation trench MOSFET platform engineered for switching power conversion; compared to planar MOSFETs of the same voltage class, OptiMOS 5 devices deliver lower RDS(on), lower gate charge (Qg), lower output charge (Qoss), and better Figure-of-Merit (FOM = RDS(on) × Qg), which translates directly into reduced conduction and switching losses. The "LS" in the part number denotes the logic-level gate variant, allowing full enhancement at VGS = 4.5 V — critical for direct microcontroller GPIO drive in 5 V and 3.3 V systems. Key differentiating specifications include 9.4 mΩ max RDS(on) at VGS=10 V, ultra-low Qg (typical ~9 nC) for fast switching edges, an integrated Schottky-like body diode with low Qrr for reduced dead-time losses in half-bridge topologies, and a 36 W power dissipation rating at TC=25 °C.

BSC097N06NSATMA1 - 60V N-Channel OptiMOS 5 MOSFET | Infineon
The Infineon BSC097N06NSATMA1 is a 60 V N-channel power MOSFET built on Infineon's OptiMOS™ 5 technology, housed in a SuperSO8 (PG-TDSON-8-6) 5x6 mm package with an exposed drain pad. It delivers up to 46 A continuous drain current at 25°C case temperature, an exceptionally low maximum on-resistance of 9.7 mOhm at VGS=10 V, and a pulsed drain current capability suited to switching converter and motor-drive transient loads. According to the Infineon product page, the part is rated for 2.5 W dissipation on the PCB (Ta) and 36 W on the case (Tc), giving designers flexibility between SMT-only designs and heatsink-attached layouts. A power MOSFET is a voltage-controlled semiconductor switch that uses an electric field at the gate to control current flow between drain and source. It belongs to the discrete semiconductor hierarchy: transistor -> FET -> MOSFET -> power MOSFET -> N-channel enhancement-mode power MOSFET. Modern trench MOSFETs like OptiMOS 5 use advanced cell geometries and thin epitaxial layers to minimize both conduction loss (RDS(on)) and switching loss (Qg, Qgd), which together determine converter efficiency at high switching frequencies. Key differentiating features include a typical gate charge of about 8 nC, an avalanche-rated body diode, 100% Rg-tested production flow, and an operating junction temperature range of -55°C to +150°C. The SuperSO8 footprint offers a superior thermal path versus standard SO-8 because the drain tab is the copper pad underneath the package, enabling PCB-side cooling without changing the silicon. These characteristics make the device competitive in 48 V telecom, server, and e-mobility auxiliary rails where every milliohm of RDS(on) translates directly into watts of loss. Architecturally, the OptiMOS 5 cell uses a deep-trench structure with a lightly doped drift region and a split-gate field plate to balance RDS(on) against switching loss. The resulting figure of merit (FOM = RDS(on) x Qg) is one of the best in its voltage class, allowing 100 kHz+ hard-switched or 1 MHz+ soft-switched topologies without exceeding package thermal limits. Typical applications include DC-DC converters for telecom/datacom, motor drive half-bridges in e-bike and small-EV inverters, synchronous rectification in 48 V isolated bus converters, hot-swap and OR-ing controllers in server CRPS rails, and Class-D audio amplifier output stages. The wide SOA margin also makes it suitable for battery protection in 12-48 V Li-ion packs where brief short-circuit events must be survived. When designing with this MOSFET, ensure the gate driver can source and sink at least 2-4 A peak to charge the gate quickly and minimize the miller plateau dwell time. Keep the gate-loop inductance under 5 nH by placing the driver physically adjacent to the gate pin and using a tight gate-to-source return path.

The part is optimized for synchronous rectification in switched-mode power supplies, where its low RDS(on) and reduced output capacitance deliver up to 43% lower conduction losses and 44% lower switching losses versus the previous generation, enabling higher system efficiency and increased power density. A power MOSFET is a voltage-controlled semiconductor switch used to convert and regulate electrical energy in power-electronics circuits. The OptiMOS 5 family sits in the broader hierarchy of N-channel enhancement-mode MOSFETs, which in turn are part of discrete power semiconductors and the wider power-management ecosystem that includes gate drivers, DC-DC controllers, and synchronous-rectifier ICs. By combining a 100V breakdown rating with sub-10 mOhm on-resistance in a compact 5x6 mm outline, the BSC098N10NS5 family targets high-current, high-frequency converter stages where traditional planar MOSFETs would be too lossy or too large. Key differentiating specifications of the BSC098N10NS5ATMA1 include its 100 V drain-source rating, 9.8 mOhm maximum RDS(on) at VGS=10 V, 60 A continuous drain current at Tc, a typical diode forward voltage of 0.9 V (VSD at IF=30 A), and a 240 A pulsed diode current rating. The device's reduced parasitic capacitances, particularly Coss, lower switching losses at high frequencies and reduce dead-time losses in half-bridge topologies. Its 100V rating provides ample headroom for 48V telecom rails, automotive 48V mild-hybrid systems, and industrial 24V/36V bus converters. Architecturally, the OptiMOS 5 platform uses Infineon's latest trench-cell geometry and a refined gate-oxide process to shrink cell pitch while maintaining avalanche ruggedness and improving body-diode recovery softness. This translates directly to the 43% RDS(on) reduction and 44% output-capacitance reduction highlighted in the datasheet's headline metrics, and to a robust 100% UIS-tested design suitable for repetitive hard-switching loops. The SuperSO8 5x6 footprint also features a large exposed drain pad that doubles as a thermal pad, allowing the part to dissipate the 69 W (Tc) maximum with a properly designed PCB copper area. Typical applications include synchronous rectification in 48V step-down (buck) and full-bridge converters for telecom and datacom equipment, secondary-side synchronous rectification in isolated DC-DC bricks for servers, motor-drive half-bridges in 24V/36V industrial and e-mobility platforms, hot-swap and OR-ing switches in redundant power systems, and low-voltage high-current power-paths in solar and battery-management systems. The 100V rating and 60A current capability also make it a strong fit for USB-PD and high-wattage adapter designs where multiple paralleled MOSFETs must be avoided to save board area. When designing with this MOSFET, ensure the gate-drive voltage reaches the full 10 V enhancement level to achieve the rated 9.8 mOhm on-resistance; 4.5 V VGS operation is supported but increases RDS(on) significantly. Use a Kelvin-source connection (the SuperSO8 5x6 has a dedicated source-sense pin) when the part is switching above 100 kHz, and lay out the high-di/dt loop (input cap, high-side FET, low-side FET) with minimum parasitic inductance to limit voltage overshoot and ringing.

A MOSFET array is a semiconductor device that integrates two or more discrete MOSFET transistors into a single package, sharing a common drain, source, or gate configuration. Arrays simplify PCB layout, reduce parasitic inductance between half-bridge switches, and shrink the total solution footprint. In the broader taxonomy, MOSFET arrays sit under discrete semiconductors -> MOSFETs -> power MOSFETs -> synchronous FET arrays. Compared with using two separate DFN MOSFETs, an integrated array halves the loop area of the high-current switching path, which directly suppresses ringing and switching losses in buck/boost converters. Key features of the BSC0993NDATMA1 include OptiMOS 5 30V technology, 17A continuous drain current, low Rds(on) typical of the OptiMOS 5 family, integrated ESD protection, and a thermally enhanced PG-TISON-8 exposed-pad package that lowers junction-to-ambient thermal resistance. The compact 5 mm x 6 mm package footprint allows direct drop-in replacement of competing dual N-channel arrays. The OptiMOS 5 architecture uses Infineon's advanced trench cell design that shrinks die area per mOhm while improving switching figures-of-merit (Qg x Rds(on)). This array is particularly suited for synchronous buck converters where the low-side and high-side FETs are co-packaged for minimal gate-loop inductance.

According to the verified Infineon datasheet, the device delivers a continuous drain current of 11.3A (Tc) and a power dissipation of 50W (Tc), with a low on-state resistance that minimizes conduction losses. The part belongs to Infineon's 200V OptiMOS family, which targets synchronous rectification in 48V telecom and server bus architectures, DC-DC converters, uninterruptible power supplies (UPS), and DC motor drive inverters. A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled semiconductor switch that uses an electric field at the gate to control current flow between the drain and source terminals. Power MOSFETs are a sub-class of discrete semiconductors and a building block of power management ICs, voltage regulators, and motor-driver modules. Within the MOSFET family, N-channel enhancement-mode devices are the most common high-side and low-side switches because their lower on-resistance per unit area translates into higher efficiency and smaller thermal footprint than equivalent P-channel parts. The BSC12DN20NS3GATMA1's 200V drain-source rating places it in the mid-voltage tier, suitable for 48V bus systems, telecom secondary-side rectification, and 100-150V battery-powered industrial platforms. Key electrical features include 200V VDS(max), 11.3A continuous drain current, a gate threshold optimized for standard 10V drive, and ultra-low figure-of-merit for high-frequency operation. The PG-TDSON-8-5 package with exposed pad provides low thermal resistance, enabling direct PCB copper heatsinking without an external heatsink in many designs. The combination of low gate charge, low output charge, and low on-resistance makes this part well-suited for hard- and soft-switching topologies at switching frequencies from 100 kHz up to several hundred kHz. The architecture uses Infineon's advanced OptiMOS silicon process, which balances conduction loss and switching loss to maximize efficiency across the load range. The chip's cell-density optimization reduces RDS(on) and gate charge simultaneously, an important metric for hard-switched converters where switching loss dominates at light load and conduction loss dominates at full load. This dual optimization distinguishes 200V OptiMOS from older-generation MOSFETs and is the reason the family is specified in 48V point-of-load and synchronous-rectification reference designs. Typical applications include 48V synchronous rectification in telecom and data-center power stages, primary-side switches in DC-DC converters, UPS low-voltage battery-side switches, and half-bridge / full-bridge inverters for DC motor drives. The 200V rating provides substantial margin above nominal 48V bus rails, improving robustness against transient over-voltage events. When designing with this MOSFET, calculate both conduction loss (I²·RDS(on)) and switching loss (driven by gate charge and VDS rise/fall times) at the operating frequency, and verify that the PCB layout minimizes source-inductance loop area. Always check the SOA curve at the worst-case operating point to ensure adequate margin during start-up and fault transients.

JEDEC FR-4 reference footprint (Ta) rising to 52 W at Tc. The logic-level gate drive threshold (VGS(th) typically well below 2.5 V at 250 uA) means the part can be driven directly from 3.3 V or 5 V microcontroller PWM outputs, removing the need for a gate-driver IC in many low-power synchronous buck or hot-swap paths. What is an OptiMOS 5 power MOSFET? OptiMOS is Infineon's family of low-voltage power MOSFETs optimized for high-frequency switching power conversion. In the system hierarchy, a power MOSFET is a discrete semiconductor that switches current between source and drain under gate control; it sits beneath DC-DC converters, motor drives, and load switches in the power-management tree. Logic-level variants (the L in the part number) accept low gate-drive voltages, enabling direct interface with microcontrollers and low-voltage PWM controllers. OptiMOS 5 is the 5th-generation refinement that reduces RDS(on) x Qg figure-of-merit versus OptiMOS 3 and 4, enabling both higher efficiency and smaller magnetics at the same load.

The OptiMOS 5 trench process delivers lower switching losses than previous generations and improved avalanche ruggedness for unclamped inductive switching events. The architecture uses an advanced trench-based cell structure that maximizes silicon utilization for low on-state loss while keeping gate charge low to minimize switching loss at high frequencies. Combined, the low RDS(on) x Qg product translates to cooler operation and higher efficiency in hard-switched topologies such as buck converters, half-bridges, and synchronous rectifiers. Typical applications include 48 V telecom hot-swap and OR-ing, USB-PD and adapter buck stages, motor drive half-bridges for eMobility and small BLDC fans, synchronous rectification in isolated DC-DC modules, and battery protection FETs in 12 V / 24 V eTools. The wide VDS margin and small footprint also suit point-of-load conversion in industrial PLC and server auxiliary rails. When designing with this MOSFET, carefully size the gate-drive loop and place a 10-100 nF ceramic bypass close to the gate-source terminals. Confirm SOA at the worst-case ID, VDS, and pulse duration for hot-swap, and respect the Tc=25 C absolute rating derating curve above 25 C case. Keep the source-sense return path short to avoid parasitic inductance that can cause VGS ringing during fast switching transitions.

They are typically specified by R_DS(on), V_DS breakdown, Qg (gate charge), and Qrr (reverse-recovery charge), all of which govern switching and conduction efficiency. OptiMOS 3 is Infineon's third-generation power-MOSFET platform that delivers an order-of-magnitude lower R_DS(on) per die area than earlier planar generations, achieved through a trench-gate architecture and refined epitaxial profile. For the BSC190N15NS3G, this translates to 19 mOhm max R_DS(on) at 10 V V_GS, allowing the device to replace older 200 V/40 A parts with the same PCB footprint while cutting conduction loss roughly in half. Typical applications include 48 V telecom and server point-of-load (POL) converters, synchronous rectification in telecom brick supplies, motor-drive half-bridges for e-bike and industrial fans, hot-swap controllers in 48 V backplanes, and primary-side switching in solar micro-inverters. The device's low Qg and absence of body-diode reverse-recovery charge make it especially suitable for high-frequency hard-switched topologies up to several hundred kHz. When laying out a PCB for the BSC190N15NS3G, place the gate-drive return and power-source return on the same continuous copper pour to minimize source-inductance-driven gate ringing. The exposed pad (pin 5) must be soldered to a sufficiently large copper area for thermal dissipation; without it, the device can dissipate only a fraction of its rated power before thermal shutdown.
