BUK7Y2R0-40HX-VB Product details
Back to previous pageProduct introduction：
The BUK7Y2R0-40HX-VB is a Single N-MOSFET deeply optimized for low-voltage, high-current power switching applications. Using advanced SGT (Split Gate Trench) technology, it balances extremely low conduction losses with excellent switching characteristics. The LFPAK56 (Power-SO8) package achieves an excellent balance between thermal dissipation and board space. The combination of 40V voltage rating, 150A current capability, and 0.7mΩ on-resistance makes it an ideal choice for applications like server power supplies, automotive electrical systems, and high-power DC-DC converters, especially suitable for scenarios with stringent requirements on heat dissipation and power density.

VDS=40V: Suitable for 12V/24V/36V systems, providing margin for voltage spikes, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 5V~12V logic levels, can be directly connected to drivers/controllers, simplifying gate drive design.
Vth=3V (typical): Moderate threshold voltage effectively suppresses dv/dt induced turn-on, while ensuring full conduction under strong drive.
RDS(on)=0.7mΩ @ VGS=10V: Ultra-low on-resistance, extremely low full-load conduction losses, significantly reducing device temperature rise, allowing for fewer paralleled devices and smaller heatsinks.
ID=150A: Robust continuous current capability, meeting steady-state and transient requirements of high-power loads with ample margin.
Package LFPAK56: Low parasitic inductance and thermal resistance, supports high-density current output, compatible with standard Power-SO8 pad layout, beneficial for thermal design and PCB layout.
Domain and module applications：
Server/Data Center Power Supplies: Replaces multiple paralleled MOSFETs in 12V synchronous rectification Buck converters, significantly reducing conduction losses, improving power conversion efficiency and density.
Automotive Electrical Systems: 40V voltage rating adapts to 12V/24V vehicle buses, 150A high current capability supports main power distribution, electric power steering, and heating load drives.
Battery Protection and BMS: Extremely low internal resistance reduces protection board self-heating, high current capability matches the high-rate charge/discharge needs of energy storage and power battery packs.
Power Tools and Low-Voltage Motor Drives: SGT technology provides low switching losses, supporting high-frequency PWM control, resulting in smoother motor operation and significantly reduced controller temperature rise.
High-Power DC-DC Converters: Replaces traditional Schottky diodes or multiple paralleled MOSFETs in synchronous rectification, improving heavy-load efficiency by 2-4%, facilitating module miniaturization.
Industrial Power Supplies and UPS: High reliability and strong overcurrent capability, suitable for continuous high-power output and short-term overload impact scenarios.
Selection Summary: The BUK7Y2R0-40HX-VB achieves an ideal balance between ultra-low on-resistance, high current carrying capability, and advanced packaging. It is a high-performance general-purpose choice for 40V low-voltage, high-power switching applications, particularly suitable for projects with extreme requirements on efficiency, temperature rise, and power density.
