IRLML2402TR 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 terminal of the N-channel MOSFET; the datasheet limits gate-to-source voltage to ±12 V (VGS). |
| 2 | S | passive | SOURCE terminal of the MOSFET; the datasheet rates continuous source (body diode) current IS at 0.54 A. |
| 3 | D | passive | DRAIN terminal of the MOSFET; the datasheet rates continuous drain current ID at 1.2 A (TA=25°C) and pulsed drain current IDM at 7.4 A. |
