IRLML9303TR from UMW, in a SOT-23. 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 of the -30 V P-channel MOSFET; gate-to-source voltage is rated ±20 V. |
| 2 | S | passive | SOURCE of the MOSFET; continuous source (body diode) current is rated -1.3 A and pulsed source current -12 A. |
| 3 | D | passive | DRAIN of the MOSFET; drain-source voltage is rated -30 V with continuous drain current of -2.3 A at TA=25°C (VGS=-10V). |
