**TECH PUBLIC** · MOSFETs · TO-252

TPSTD86N3LH5 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; gate-source voltage is rated at ±20V maximum with a typical threshold of 1.4V (0.8V min, 2.0V max) at VDS=VGS, ID=250µA. |
| 2 | D | passive | Drain, also the metal tab; drain-source voltage is rated at 30V maximum with 90A continuous drain current at TC=25°C. |
| 3 | S | passive | Source; maximum continuous body-diode forward current is 90A. |
