IRLML9303TRPBF-HXY

HXY MOSFET · MOSFETs · SOT-23

IRLML9303TRPBF-HXY from HXY MOSFET, 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 P-channel MOSFET, with gate-source voltage limited to ±20 V and operation stated down to gate voltages as low as 2.5 V.
2 S passive Source of the P-channel MOSFET, with continuous source current rated -3.2 A and pulsed -13 A through the body diode.
3 D passive Drain of the P-channel MOSFET, rated VDS = -30 V and continuous drain current ID = -4.1 A (pulsed -13 A).
