**STMicroelectronics** · MOSFETs · TO-220FP

STF100N10F7 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 of the N-channel MOSFET, with gate-source voltage limited to ±20 V (VGS, Table 1). |
| 2 | D | passive | Drain of the N-channel MOSFET, rated for 100 V drain-source voltage and 45 A continuous drain current at TC = 25 °C on the TO-220FP variant (Table 1). |
| 3 | S | passive | Source of the N-channel MOSFET; the datasheet gives no source-specific limit beyond the device ratings in Table 1. |
