BUK9E1R8-40E,127-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power DC-DC converter or automotive electronics module that needs to handle load currents of up to 150A while minimizing conduction losses? Ordinary MOSFETs either have high on-resistance, leading to severe heat generation, or insufficient withstand voltage, raising reliability concerns. The VBsemi BUK9E1R8-40E,127-VB is designed for this—it integrates 40V withstand voltage, 150A current-carrying capability, and an on-resistance of only 1.7mΩ in a TO262 package, allowing high-power-density designs to no longer compromise on heat dissipation and efficiency.
