FDD8586

UMW · MOSFETs · TO-252

FDD8586 from UMW, 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 of the N-channel MOSFET; the absolute maximum gate-to-source voltage VGS is ±20 V.
2 D passive DRAIN terminal; absolute maximum drain-to-source voltage VDS is 20 V and continuous drain current is rated 35 A (package limited) and 93 A (die limited).
3 S passive SOURCE terminal, the reference for the gate-to-source voltage; the datasheet gives no separate pin-specific limits for this terminal.
