IRLML5203TR

UMW · MOSFETs · SOT-23

IRLML5203TR 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 -30 V P-channel MOSFET; gate-source voltage is rated VGS = ±20 V.
2 S passive SOURCE terminal of the -30 V P-channel MOSFET; drain-source voltage is rated VDS = -30 V.
3 D passive DRAIN terminal of the MOSFET; rated for continuous drain current ID = -3 A and pulsed drain current IDM = -24 A.
