AGMH70N70C

AGM-Semi · MOSFETs · TO-220

AGMH70N70C from AGM-Semi, in a TO-220. 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; controls the channel, with absolute maximum VGS of ±20 V and threshold VGS(th) of 2.0 to 4.0 V.
2 D passive Drain (also connected to the metal tab); rated for VDS of 68 V and continuous ID of 69 A at Tc=25℃.
3 S passive Source; body-diode source-drain current up to 69 A.
