AO3422A

UMW · MOSFETs · SOT-23

AO3422A 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 GATE input Gate terminal of the N-channel MOSFET; gate-source voltage is rated ±12 V, and the device is specified for gate drive from 2.5 V to 12 V.
2 SOURCE passive Source terminal of the N-channel MOSFET; continuous source-drain diode current is rated at IS = 0.85 A.
3 DRAIN passive Drain terminal of the N-channel MOSFET; drain-source voltage is rated at 60 V, with continuous drain current ID = 2.1 A and pulsed drain current IDM = 10 A.
