IRF4905STRLP from UMW, in a TO-263. 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 gate-to-source voltage is rated VGS = ±20 V. |
| 2 | D | passive | DRAIN terminal; VDS = -55 V with continuous drain current ID = -42 A (package limited/silicon limited ratings as stated in the absolute maximum table). |
| 3 | S | passive | SOURCE terminal; body-diode source current IS = -42 A and pulsed source current ISM = -280 A. |
