SSP45N20B-VB

VBsemi Elec · MOSFETs · TO-220AB

SSP45N20B-VB from VBsemi Elec, in a TO-220AB. 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 ±25 V (absolute maximum), with gate-body leakage tested at VGS = ±20 V.
2 D passive Drain (also connected to the tab); drain-source voltage is rated at 200 V with continuous drain current of 50 A at TC = 25 °C.
3 S passive Source; connects to the source terminal of the N-channel MOSFET, with pulsed source current ISM of 36 A.
