SWB020R03VLT

Samwin · MOSFETs · TO-263

SWB020R03VLT from Samwin, in a TO-263. 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 Gate input Gate terminal of the N-channel MOSFET; gate-to-source voltage limited to ±20 V with threshold of 1.2 to 2.4 V.
2 Drain passive Drain terminal; drain-to-source voltage up to 30 V and continuous drain current of 180 A (limited by junction temperature) at TC=25°C.
3 Source passive Source terminal of the N-channel MOSFET; continuous body-diode source current of 180 A.
