IRLR7843TR 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's absolute maximum gate-to-source voltage is VGS = ±20 V. |
| 2 | D | passive | DRAIN terminal; the datasheet's absolute maximum drain-source voltage is VDS = 30 V, with continuous drain current ID = 161 A at TC = 25°C (VGS = 10 V). |
| 3 | S | passive | SOURCE terminal; the reference terminal for VGS and VDS, with the maximum drain-source voltage of 30 V given in the absolute maximum ratings. |
