AOD8N25

Alpha & Omega Semicon · MOSFETs · TO-252

AOD8N25 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; maximum gate-source voltage is ±30 V, with RDS(ON) specified at VGS=10 V.
2 D passive Drain (also connected to the tab); maximum drain-source voltage is 250 V with 8 A continuous current at TC=25°C.
3 S passive Source; body-diode continuous current is 8 A maximum.
