FDBL86363-F085-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power motor driver or automotive-grade DC-DC converter where the PCB needs to carry hundreds of amperes of current while strictly controlling conduction losses? Ordinary MOS transistors either have high internal resistance leading to thermal runaway, or are too large in package to layout easily. The VBsemi FDBL86363-F085-VB is designed for this purpose – it integrates 80V withstand voltage, 350A current carrying capacity, and an on-resistance of only 1mΩ in a TOLL high-current package, making high-power-density design uncompromising.
