AOSS32334C

Alpha & Omega Semicon · MOSFETs · SOT-23-3

AOSS32334C from Alpha & Omega Semicon, in a SOT-23-3. 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; ESD-protected, VGS maximum ±20V, with threshold of 1.3V min to 2.3V max at ID=250µA.
2 S passive Source; the body diode runs from source to drain, with continuous body-diode current up to 2A.
3 D passive Drain; VDS maximum 30V, continuous ID 6.2A at TA=25°C, pulsed IDM 40A.
