SWF4N70D

Samwin · MOSFETs · TO-220F

SWF4N70D from Samwin, 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 Gate input Gate terminal of the N-channel MOSFET, with a gate-to-source voltage rating of ±30 V and a gate threshold voltage of 2.5 V min to 4.5 V max at VDS=VGS, ID=250uA.
2 Drain passive Drain terminal with a drain-to-source voltage rating of 700 V and continuous drain current of 4 A at TC=25oC, limited by junction temperature.
3 Source passive Source terminal of the MOSFET, carrying a continuous body-diode source current of up to 4 A.
