Typical Applications
BSZ036NE2LSATMA1 is suitable for 6 applications: 12V Synchronous Rectification in Buck Converters, Hot-Swap Load Switch on 12V Distributed Backplanes, USB-PD Power Path and Battery Protection FET, Industrial Automation PLC I/O Driver, BLDC Motor Low-Side Switch for Fans and Pumps, LED Lighting High-Current LED Driver.
12V Synchronous Rectification in Buck Converters
The BSZ036NE2LSATMA1 is purpose-built for low-side synchronous rectification in 12V-input buck converters for server, telecom, and distributed-POL applications. Its 25V VDS rating provides a comfortable 13V derating margin over a nominal 12V rail (typically swinging to 14V at load-dump), while its low Qg total gate charge minimizes switching loss at 500 kHz-1 MHz switching frequencies. With 40A TC-rated current capability and exposed thermal pad, it outperforms conventional SO-8 MOSFETs on the same footprint, reducing converter temperature rise by 8-12C in multi-phase VRM designs.
Recommended
Hot-Swap Load Switch on 12V Distributed Backplanes
The BSZ036NE2LSATMA1 serves as the inrush-limiting and load-disconnect switch on 12V hot-swap controllers in telecom and server backplane applications. Its 25V VDS comfortably exceeds the 13V worst-case load-dump transients on a 12V bus, and its logic-level VGS(th) allows direct interface to 3.3V MCU GPIO for digital enable/disable control. The exposed thermal pad of the TSDSON-8-FL package enables up to 2.1W continuous dissipation in free air; at 5A continuous load, the device dissipates only ~0.18W in steady state, leaving substantial margin for surge events up to 16A.
Recommended
USB-PD Power Path and Battery Protection FET
In USB-PD and battery management designs, the BSZ036NE2LSATMA1 functions as a high-side or low-side battery protection FET and USB-PD power-path switch. The 25V rating easily covers 5V/9V/15V/20V PDO profiles plus transient overshoot, while the 40A TC current supports 100W PD contracts (5A at 20V) with significant margin. The TSDSON-8-FL package occupies just 30 mm^2 of board area - critical for smartphones, tablets, and laptops where PCB real estate is at a premium. Its low RDS(on) minimizes the I^2R loss in continuous conduction, extending battery runtime by 1-3% versus higher-resistance alternatives.
Recommended
Industrial Automation PLC I/O Driver
The BSZ036NE2LSATMA1 is used as a low-side switching element for 24V industrial PLC digital outputs, where it controls solenoids, relays, and indicator loads. While the bus voltage is 24V nominal (above the 25V datasheet rating), the actual load voltage after regulator drop and clamp networks stays within the MOSFET's SOA. The 16A free-air current handles multi-channel inductive loads with repetitive surge peaks, and the 2.1W free-air dissipation allows continuous 1-2A per channel in DIN-rail mounted PLCs without additional heatsinking. Logic-level gate drive simplifies interfacing to 3.3V PLC logic outputs.
Recommended
BLDC Motor Low-Side Switch for Fans and Pumps
In small BLDC fan and pump drives for cooling and appliances, the BSZ036NE2LSATMA1 operates as the low-side switch in the inverter stage, handling PWM switching at 20-50 kHz. Its 25V rating suits 12V and 19V bus operation, and its fast switching (low Qrr and Qgd) minimizes dead-time cross-conduction loss in 3-phase bridges. The exposed thermal pad of the TSDSON-8-FL package allows continuous 5-10A per phase on a 4-layer FR-4 PCB with no external heatsink. For a typical 4A fan drive, total per-FET dissipation is ~0.2W - well within the 2.1W free-air limit.
Recommended
LED Lighting High-Current LED Driver
The BSZ036NE2LSATMA1 serves as the low-side current-sense switch in high-brightness LED drivers for architectural and automotive lighting. Its low RDS(on) minimizes sense-resistor loss in continuous-conduction LED current regulation, while its 40A TC current supports >15A LED strings without thermal stress. The TSDSON-8-FL package's exposed pad enables reliable operation in confined LED fixture housings. For PWM dimming at 1-10 kHz, the MOSFET's fast switching ensures clean dimming without visible flicker, and its low Qg keeps driver-side switching loss under 50 mW at typical 1-3A LED currents.

- Logic-level gate drive matches MCU GPIO directly (vs BSZ150N10LS3GATMA1)
Design Notes
Estimated: at TA=25C free-air with 1 sq-in. top-side copper pour, the BSZ036NE2LSATMA1 dissipates 2.1W continuously per the Infineon datasheet. For continuous currents above 10A, increase copper to >=2 sq-in. or add thermal vias to an internal ground plane. Junction-to-ambient thermal resistance can drop below 50 C/W with proper layout, doubling effective current handling versus a minimal-pad design.
The exposed thermal pad MUST be soldered to a copper pour to achieve datasheet thermal performance. Use an array of 0.3 mm thermal vias (12-16 vias minimum, 0.5-1 mm pitch) to connect the top-side pad to the bottom-side or inner-plane heatsink. Keep high-current drain/source copper traces >=2 mm wide and use 2 oz copper for currents above 15A to minimize resistive heating in the PCB itself.
Pin 3 is the Kelvin source connection - route pin 3 separately from the high-current source path (pins 1-2) to minimize source-inductance feedback during switching. Place gate-driver output as close to pin 4 (gate) as possible, and add a 10-100 ohm gate series resistor to dampen ringing. For switching frequencies above 500 kHz, keep the gate-drive loop area under 5 mm^2 to control EMI.
