BUK7640-100A,118-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power-density industrial power supply or automotive-grade DC-DC module, where the board must withstand currents up to 45A while facing the impact of a 100V bus voltage. Ordinary MOSFETs either lack sufficient voltage tolerance or have excessive conduction losses, requiring ever-larger heatsinks. VBsemi BUK7640-100A,118-VB is designed for this purpose — it uses a large TO263 package to integrate 100V withstand voltage, 45A continuous current capability, and an on-resistance as low as 30mΩ, combined with Trench technology, allowing high-power switching applications to achieve an ideal balance between reliability and efficiency.
