FDD8870-HXY

HXY MOSFET · MOSFETs · TO-252-2L

FDD8870-HXY from HXY MOSFET, in a TO-252-2L. 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 enhancement-mode MOSFET, with VGS rated at ±20V per the absolute maximum ratings.
2 D passive Drain terminal of the N-channel MOSFET, with VDS rated at 30V per the absolute maximum ratings and a continuous drain current of 120A stated in the general features.
3 S passive Source terminal of the N-channel MOSFET; the datasheet gives no separate pin-level electrical limit for this terminal.
