K3148-VB

VBsemi Elec · MOSFETs · TO-220F

K3148-VB from VBsemi Elec, in a TO-220F. 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 terminal; gate-source voltage VGS is rated ±20 V in the absolute maximum ratings.
2 D passive Drain terminal; drain-source voltage is rated 100 V, and continuous drain current is 50 A at TC = 25 °C, limited by the package.
3 S passive Source terminal; source-drain diode continuous current is rated 50 A with pulsed current of 120 A.
