VDS=40V: Suitable for 12V/24V/36V systems, providing ample voltage margin to effectively absorb switching spikes and reduce avalanche breakdown risk.
VGS=±20V: Compatible with 4.5V~12V logic levels, supporting a wide drive range, directly controllable by MCU/gate driver IC, simplifying peripheral circuitry.
Vth=2.5V (typical): Moderate threshold voltage, balancing low-voltage drive capability and anti-interference performance, adaptable to various drive conditions.
RDS(on)=5mΩ @ VGS=10V, 6mΩ @ VGS=4.5V: Ultra-low on-resistance, minimizing conduction losses at full load, significantly reducing temperature rise, enabling smaller heatsink size or higher system power density.
ID=100A: Strong continuous current capability, meeting steady-state and transient demands of high-power loads, paired with TO263 package for efficient heat dissipation.
Package TO263: Large drain pad design, low thermal resistance, low parasitic inductance, suitable for high-current, high-frequency applications, compatible with standard PCB mounting processes for mass production.
Domain and module applications：
High-power DC-DC converters: Replaces traditional MOS in synchronous rectification or buck/boost topologies. Ultra-low on-resistance can improve heavy-load efficiency by 2-3% and reduce power stage heat generation.
Motor drive modules: 100A current margin combined with low switching losses, suitable for power tools, robots, and electric vehicle controllers, achieving smooth high-torque output.
Battery protection and power management: Fast switching characteristics ensure reliable shutdown during overcurrent/short circuits. Low internal resistance reduces self-consumption on the protection board, extending battery life.
Automotive power systems: 40V withstand voltage covers 12V/24V vehicle buses. Wide operating temperature range and low thermal resistance package adapt to high-reliability scenarios like engine compartments.
Server and communication power supplies: High efficiency and high current capability meet the stringent requirements of VRMs and rectifier modules for power MOSFETs, aiding module miniaturization.
Industrial control and electric equipment: High-reliability Trench technology adapts to frequent switching and surge loads, reducing system failure rates and extending equipment life.
Selection Summary: The BUK968R3-40E,118-VB, with its ultra-low on-resistance, 100A high current capability, and excellent thermal characteristics of the TO263 package, is a high-performance first choice for 40V low-voltage high-power switching applications, especially suitable for projects with extreme demands on efficiency, thermal management, and reliability.
