HUF75639S3S-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter or motor drive module, and the PCB needs to handle both high current carrying capacity and low heat generation. Ordinary MOSFETs either lack sufficient voltage tolerance or have high on-resistance, leading to uncontrolled system temperature rise. VBsemi HUF75639S3S-VB is designed for this—it integrates 100V withstand voltage, 70A current capability, and an on-resistance of only 20mΩ into the TO263 high-current package, allowing high-power-density designs without compromise.
