BUK663R2-40C,118-VB Product details
Back to previous pageProduct introduction：
Are you looking for a power switch that can handle large currents while maintaining extremely low losses? Whether in automotive power supplies, motor drives, or high-power DC-DC conversion, traditional MOSFETs often cause headaches in balancing conduction losses and thermal design. The VBsemi BUK663R2-40C,118-VB is designed for this purpose—it combines a 40V withstand voltage, 150A current carrying capacity, and an on-resistance of only 2mΩ, integrated into a TO263 (D2PAK) high-power package, allowing high power density designs to no longer compromise.

Domain and module applications：
Automotive electronics / body control – Used for high-current load switches such as windows, fans, and seat motors. Low conduction voltage drop effectively reduces temperature rise and improves system reliability.
Power tools / garden machinery – Serves as the power-stage switch in brushless motor drivers, withstanding high current surges to ensure stable long-term operation under heavy loads.
High-power DC-DC converters – Replaces Schottky diodes in synchronous rectification topologies, significantly reducing conduction losses and improving conversion efficiency.
Battery protection / power management – Used in charge/discharge circuits of lithium battery packs or energy storage systems. Milliohm-level internal resistance reduces energy loss and supports high-current switching.
Server power supplies / communication power supplies – Functions as the main switch or rectifier in 48V/12V intermediate bus converters, meeting high reliability requirements.
Industrial control / variable frequency drives – Enables motor speed control with PWM. Low RDS(on) allows for smaller heat sinks and more compact equipment.
UPS / inverters – Acts as a high-frequency switching device, handling high-power transmission and improving system overload capacity and efficiency. One-sentence summary: The BUK663R2-40C,118-VB is not an ordinary MOSFET; it is the "low-resistance tool" and "efficiency engine" for your high-current, low-voltage power designs.
