STF45N65M5

STMicroelectronics · MOSFETs · TO-220FP

STF45N65M5 from STMicroelectronics, in a TO-220FP. 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 of the N-channel MOSFET; the gate-source voltage is rated at ±25 V (VGS).
2 D passive Drain terminal of the N-channel MOSFET; continuous drain current is 35 A at TC = 25 °C and drain-source breakdown voltage V(BR)DSS is 650 V minimum.
3 S passive Source terminal of the N-channel MOSFET, the reference for the gate-source voltage (±25 V maximum).
