BSZ150N10LS3GATMA1 - 100V N-Ch OptiMOS 3 MOSFET | Infineon
MPN: BSZ150N10LS3GATMA1 ✓ Hoạt độngBSZ150N10LS3GATMA1 Tóm tắt
A power MOSFET is a voltage-controlled semiconductor switch that uses a gate field to modulate current flow between the source and drain terminals. N-channel enhancement-mode MOSFETs such as this part are the workhorse switching element in synchronous buck/boost converters, half-bridges, and full-bridges on the low-side position, where their low gate charge and low on-resistance translate directly into lower conduction and switching losses. Within the broader component hierarchy, MOSFETs sit under discrete semiconductors, then transistors, then power switches, and ultimately under the power-management umbrella of a complete electronic system.
Key differentiating features of the BSZ150N10LS3GATMA1 include 100 V drain-source voltage, 40 A continuous drain current, 15 mΩ maximum RDS(on) at VGS=10 V, an ultra-low on-resistance per unit area thanks to the OptiMOS 3 trench process, an exposed drain pad (PG-TSDSON-8) for very low thermal resistance, and a logic-level compatible gate threshold range. The part is also RoHS compliant and supports lead-free reflow profiles up to 260 °C peak.
From an architectural standpoint, the PG-TSDSON-8 (Power-TDFN) package places the silicon die on an exposed lead-frame paddle that doubles as the drain connection, so the entire bottom of the package acts as a thermal path to the PCB copper. This drastically shrinks the RthJA versus traditional SO-8 packages and enables the 63 W Tc rating in a footprint of only about 3.3 x 3.3 mm. The OptiMOS 3 cell structure also provides excellent body-diode ruggedness, which matters for synchronous-rectifier and bridge applications where the intrinsic diode carries current during dead-time.
Typical applications include high-frequency DC/DC converters, synchronous rectification in 48 V telecom and server power supplies, motor-drive H-bridges (12 V / 24 V / 48 V systems), battery management and protection FETs, hot-swap and e-fuse circuits, and Class-D audio amplifier output stages. The 100 V rating also makes it attractive for industrial 24 V/36 V bus converters where inductive voltage transients must be tolerated.
When designing with this MOSFET, pay close attention to gate-drive voltage: the OptiMOS 3 family is specified for 10 V VGS to reach its lowest RDS(on), and at 4.5 V VGS the on-resistance rises noticeably. Also plan thermal copper area under the exposed pad — the 2.1 W TA rating is only achievable with a properly designed PCB land pattern, and derate aggressively above 25 °C ambient.

Ứng dụng tiêu biểu
BSZ150N10LS3GATMA1 phù hợp cho 6 Áp dụngs: 48 V Synchronous Rectifier, Motor Drive H-Bridge (24 V / 48 V), Hot-Swap / e-Fuse Controller Switch, Class-D Audio Amplifier Output Stage, Battery Management / Protection FET, Industrial 24 V/36 V DC/DC Converter.
48 V Synchronous Rectifier
The BSZ150N10LS3GATMA1 is well suited to 48 V secondary-side synchronous-rectifier stages in telecom and server SMPS, where its 100 V VDS rating provides comfortable headroom above 48 V plus inductive spikes, and its 15 mΩ maximum RDS(on) keeps conduction loss at 24 W at 40 A full load. Placed as the low-side MOSFET in a buck-derived half-bridge driven by an Infineon EiceDRIVER gate IC, the part delivers sub-100 ns switching transitions thanks to the OptiMOS 3 cell geometry. The PG-TSDSON-8 package keeps the power loop inductance low, reducing overshoot and EMI compared with larger SO-8 parts. The 63 W TC power dissipation figure allows continuous 20–25 A operation with proper PCB copper, which is the typical operating point of a 48 V-to-PoL intermediate bus converter.

Motor Drive H-Bridge (24 V / 48 V)
The BSZ150N10LS3GATMA1 works as the low-side switch in 24 V or 48 V brushed-DC and PMSM motor H-bridges, where its 100 V rating tolerates regen transients and the 40 A continuous current supports motors in the 200–500 W mechanical output range. Its 15 mΩ RDS(on) minimizes conduction loss at high duty cycle, extending battery runtime in cordless tools and e-mobility platforms. The PG-TSDSON-8 footprint enables compact four-MOSFET bridges in roughly 80 mm² of board area, which is critical for handheld power tools. The exposed drain pad couples directly to inner-layer copper for sustained 20 A continuous operation without an external heatsink.

Hot-Swap / e-Fuse Controller Switch
The BSZ150N10LS3GATMA1 functions as the pass/ProtectFET in 48 V hot-swap and electronic fuse circuits, where its 100 V VDS handles standard telecom bus voltages with margin and its 15 mΩ RDS(on) limits steady-state voltage drop to about 75 mV at 5 A. The 40 A pulsed current capability absorbs inrush transients when bulk capacitors charge. The PG-TSDSON-8 footprint allows a compact 3.3 x 3.3 mm solution that fits on SMD adapter cards and high-availability server backplanes. Designers should add a TVS clamp or active gate slew-rate control to keep VDS within the 100 V rating during hot-plug events.

Class-D Audio Amplifier Output Stage
The BSZ150N10LS3GATMA1 is well matched to the output half-bridge of sub-100 V Class-D audio amplifiers, where its 15 mΩ RDS(on) and 40 A peak current deliver high efficiency (>90%) and low THD+N at 200–400 W output. The PG-TSDSON-8 package minimizes switching-loop inductance, which is critical for clean PWM edges and reduced EMI in audio-band applications. The exposed drain pad enables direct PCB heatsinking so the amplifier can deliver continuous power without an external heatsink. Designers should pair this part with a dedicated Class-D gate driver such as the IRS2092 family for self-oscillating or PWM-modulated topologies.

Battery Management / Protection FET
The BSZ150N10LS3GATMA1 acts as the low-side protection FET in 48 V lithium-ion battery packs for e-bikes, light EVs, and stationary storage, where its 100 V VDS handles pack transients and its 15 mΩ RDS(on) limits continuous discharge loss to about 0.5% at 30 A. The 40 A current rating matches mid-power pack architectures in the 1–3 kWh range. The PG-TSDSON-8 footprint allows a compact BMS PCB layout with minimal trace resistance, critical for accurate coulomb counting. The part is specified for -55 °C to +150 °C junction, covering the full automotive and industrial temperature range.

Industrial 24 V/36 V DC/DC Converter
The BSZ150N10LS3GATMA1 is ideal for industrial 24 V and 36 V bus DC/DC converters used in factory automation, robotics, and process control, where its 100 V VDS easily tolerates the 36 V nominal bus plus 50% transient over-voltage events defined in IEC 61131-2. The 15 mΩ RDS(on) and 40 A rating enable single-MOSFET synchronous stages at the 300–500 W power level. The PG-TSDSON-8 footprint allows a highly compact solution suitable for DIN-rail mounted power supplies where PCB area is at a premium. The exposed drain pad couples directly to a topside copper pour for natural convection cooling, eliminating the need for an external heatsink in most configurations.

Ghi chú thiết kế
The 2.1 W TA dissipation rating assumes a 4-layer FR4 PCB with at least 1 oz copper and 1 square inch of drain-pad copper area. Estimated: at 1 W dissipation and a 50 °C ambient, the junction temperature rise above ambient is roughly RthJA * Pdiss, where RthJA is approximately 60 °C/W on a JEDEC EIA/JESD51 1-square-inch test board. For continuous 10+ A operation, extend the drain copper to multiple square inches and add thermal vias to inner layers. Without proper copper, the part will throttle or fail in a few minutes at full current.
Use a PG-TSDSON-8 land pattern that exposes the drain pad to a copper pour as large as thermal constraints allow. Stitch the exposed pad with a 3x3 array of 0.3 mm thermal vias to inner-layer copper. Keep the gate loop (gate driver output → gate resistor → gate pin → source pin → gate driver ground) under 5 mm total length to avoid gate ringing. The source pins should share a low-inductance connection to the gate-driver ground return, NOT the system power ground.
Do not assume the part can switch at full 40 A continuously at TA=25 °C — the 40 A rating is at TC=25 °C, which requires substantial copper. At TA=85 °C the continuous current derates to about 15 A on a typical 1-square-inch copper pour. Also avoid operating VGS above ±20 V absolute maximum; use a gate-source Zener or dedicated gate-driver clamp if the gate is exposed to high dV/dt transients. Finally, do not connect the gate to a high-impedance node when not driven, as the part can partially turn on from leakage and cause shoot-through.
