Alpha Omega Semicon · MOSFETs · SOT-323

AO7401 from Alpha Omega Semicon, in a SOT-323. 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; drives the P-channel MOSFET with VGS rated ±12V maximum and usable down to -2.5V (RDS(ON) < 200mΩ at VGS=-2.5V).
2 S passive Source of the P-channel MOSFET; body diode continuous current is -0.5A maximum.
3 D passive Drain; VDS rated -30V maximum with continuous drain current of -1.4A at TA=25°C and pulsed -10A.
