Product introduction：
BUK752R3-40E,127-VB is a Single N-MOSFET deeply optimized for low-voltage, high-power switching scenarios. The Trench technology achieves extremely low on-resistance while maintaining excellent switching characteristics. The TO220 package offers superior heat dissipation and overcurrent capability. The combination of 40V voltage rating, 180A continuous current, and 2mΩ on-resistance makes it a cost-effective core power device for applications such as low-voltage, high-current power paths, motor drives, and battery protection, especially suitable for industrial and automotive-grade solutions with stringent loss and temperature rise requirements.

VDS=40V: Suitable for 12V/24V/36V systems, providing ample margin for switching spikes and load transients, enhancing system robustness.
VGS=±20V: Compatible with standard gate drives and 10V~12V logic levels, can be directly controlled by driver ICs or MCUs via drivers, simplifying peripheral design.
Vth=3V (Typical): Reasonable threshold voltage setting, effectively suppresses dv/dt induced turn-on, while ensuring full conduction under strong drive.
RDS(on)=2mΩ @ VGS=10V: Milliohm-level on-resistance, extremely low conduction loss, significantly reduced temperature rise at full load, allowing for smaller heatsinks.
RDS(on)=15mΩ @ VGS=4.5V: Maintains controllable conduction capability under low gate drive voltage conditions, meeting redundancy requirements for various drive scenarios.
ID=180A: Ample continuous current capability to handle high-power DC loads, motor stall conditions, and short-duration battery current surges.
Package TO220: Through-hole mounting facilitates thermal design, suitable for higher power PCB layouts, can be used with standalone heatsinks for high power density.
Domain and module applications：
High-Power DC-DC Converters: Replace multiple low-voltage MOSFETs in synchronous rectification or forward topologies, reducing conduction losses and improving heavy-load efficiency.
Battery Pack Charge/Discharge Management: Extremely low internal resistance reduces protection board heat generation; 180A high current supports high-rate charge/discharge, suitable for power tools and energy storage devices.
Low-Voltage High-Current Motor Drives: Low loss during PWM speed control, significantly reduced controller temperature rise; TO220 package facilitates power trace layout.
Automotive Power Systems: 40V withstand voltage covers 12V/24V automotive bus transients; wide safe operating area adapts to harsh conditions like starting and load transients.
Electric Forklift/AGV Drive Modules: High continuous current and low thermal resistance handle long-term high-load operation, improving system reliability and endurance.
High-Power Switching Power Supplies: Application in synchronous rectification stages reduces rectification losses, simplifies parallel current sharing design, and enhances power module power density.
UPS and Inverter Front-End: Ideal switch for low-voltage high-current paths, combining low conduction voltage drop and fast switching capability, enabling efficient energy conversion. Selection Summary: BUK752R3-40E,127-VB, with its 2mΩ ultra-low on-resistance, 180A high current capability, and TO220 robust heat dissipation package, is the preferred device for low-voltage high-power switching applications, especially suitable for power supply, motor, and automotive system projects with clear requirements for efficiency, temperature rise, and long-term reliability.
