IRLR9343TR from UMW, 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; the datasheet rates gate-to-source voltage VGS at ±20 V. |
| 2 | D | passive | DRAIN terminal; continuous drain current is rated at -20 A (TC=25°C) with VDS of -55 V. |
| 3 | S | passive | SOURCE terminal; the body-diode continuous source current is rated at -20 A. |
