AOD4184L

Alpha Omega Semicon · MOSFETs · TO-252-2(DPAK)

AOD4184L from Alpha Omega Semicon, in a TO-252-2(DPAK). 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 of the N-channel MOSFET; gate-source voltage is rated at ±20 V (VGS).
2 D passive Drain, electrically connected to the DPAK tab; continuous drain current is rated 50 A at TC=25°C (limited by bond wires) and VDS is 40 V.
3 S passive Source of the MOSFET; body-diode maximum continuous current is rated 20 A (IS).
