**TECH PUBLIC** · MOSFETs · TO-252

TPM3090NK3-7 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 | G | input | Gate terminal of the N-channel MOSFET, with gate-source voltage limited to ±20 V maximum and threshold voltage VGS(th) of 0.8 V min to 2.0 V max at VDS=VGS, ID=250 µA. |
| 2 | D | passive | Drain terminal, also the exposed tab of the package, rated for 30 V drain-source voltage and 90 A continuous drain current at TC=25 °C (180 A pulsed). |
| 3 | S | passive | Source terminal of the N-channel MOSFET, carrying up to 90 A continuous at TC=25 °C, with a maximum continuous body-diode forward current IS of 90 A. |
