IRLML0040TR 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; the datasheet limits gate-to-source voltage to ±16 V (VGS). |
| 2 | S | passive | SOURCE terminal; the datasheet rates continuous source (body diode) current IS at 1.3 A and pulsed source current ISM at 15 A. |
| 3 | D | passive | DRAIN terminal; the datasheet rates drain-source voltage VDS at 40 V and continuous drain current ID at 3.6 A (TA=25°C). |
