AOD4126

Alpha & Omega Semicon · MOSFET · TO-252

AOD4126 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 limited to ±25V, with VGS(th) of 2V min to 4V max at ID=250µA.
2 D passive Drain (also the exposed tab); VDS rating 100V, continuous ID 43A at TC=25°C.
3 S passive Source; body diode continuous current up to 40A.
