**STMicroelectronics** · MOSFETs · DPAK

STD20NF10T4 from STMicroelectronics, in a DPAK. 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; control input accepting ±20 V gate-source voltage to modulate drain-source conduction. |
| 2 | D | output | Drain terminal; conducts maximum 25 A continuous drain current at TC = 25 °C with 100 V maximum drain-source voltage; connected to package tab for thermal dissipation. |
| 3 | S | passive | Source terminal; reference point for gate-source voltage and drain current return path. |
