# IRLML2246TR

**UMW** · MOSFETs · SOT-23

IRLML2246TR 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 P-channel MOSFET; the datasheet rates gate-to-source voltage VGS at ±12 V maximum. |
| 2 | S | passive | SOURCE terminal of the P-channel MOSFET, which carries the body-diode source current (IS = -1.3 A continuous, ISM = -11 A pulsed per the datasheet). |
| 3 | D | passive | DRAIN terminal of the P-channel MOSFET; the datasheet rates drain-source voltage VDS at -20 V with continuous drain current ID = -2.6 A at VGS = -10 V and TA = 25°C. |
