AOD4144-MS

MSKSEMI · MOSFETs · TO-252

AOD4144-MS from MSKSEMI, 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 terminal; the gate-source voltage is rated at ±20 V (VGS).
2 D passive Drain terminal; the drain-source voltage is rated at 30 V (VDS) with 60 A continuous drain current at TC=25℃.
3 S passive Source terminal; the continuous source current is rated at 55 A (IS) and the pulsed source current at 110 A (ISM).
