**TECH PUBLIC** · MOSFETs · TO-252

TPM2517NHK3 from TECH PUBLIC, in a TO-252. 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; gate-source voltage is limited to ±20 V with threshold of 2.0 V min to 4.0 V max at ID=250µA. |
| 2 | Drain | passive | Drain terminal (also the tab); drain-source voltage is rated 250 V and continuous drain current 17 A. |
| 3 | Source | passive | Source terminal; the integral body diode carries a continuous source current of 17 A max and pulsed current of 68 A. |
