FDD6637-VB

VBsemi Elec · MOSFETs · TO-252

FDD6637-VB from VBsemi Elec, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate; gate-source voltage limit is ±20 V, with threshold VGS(th) of -1 V to -3 V at ID = -250 µA.
2 D passive Drain (center pin, also the exposed metal tab); VDS rated -30 V with continuous drain current of -70 A (package limited) at TC = 25 °C.
3 S passive Source; continuous source-diode current is -70 A and pulsed is -240 A.
