BUK714R1-40BT,118-VB Product details
Back to previous pageProduct introduction：
BUK714R1-40BT,118-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching scenarios. The Trench process balances ultra-low on-resistance with high switching speed, and the TO263 package achieves a good balance between heat dissipation capability and soldering reliability. The combination of 40V withstand voltage, 150A current carrying capacity, and 2mΩ-level on-resistance makes it a preferred device for high-power DC-DC, motor drive, and battery protection applications, especially suitable for industrial-grade and automotive-grade systems with strict requirements on conduction losses and thermal performance.
