FDI8442-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter or motor drive module, where the PCB needs to handle hundreds of amperes of current while controlling conduction loss and temperature rise. Ordinary MOS transistors either have high on-resistance or insufficient heat dissipation capability. VBsemi FDI8442-VB is designed for this—it integrates a 40V withstand voltage, 150A continuous current capability, and an on-resistance of only 1.7mΩ in a TO262 industrial-grade package, allowing high-current power designs without compromise.
