AOD444

Alpha Omega Semicon · MOSFETs · TO-252

AOD444 from Alpha Omega Semicon, in a TO-252. 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; gate-source voltage is limited to ±20 V, with RDS(ON) specified at VGS=10V (<60mΩ) and 4.5V (<85mΩ).
2 D passive Drain, connected to the exposed tab; drain-source voltage is rated 60 V with 12 A continuous drain current at TC=25°C.
3 S passive Source; the body diode is rated for 12 A maximum continuous current.

CAD (KiCad official)

  • Symbol: AOD444
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: aod444-etched.step / aod444-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); aod444.step / aod444.glb are the bare package body.
