KND3308A

KIA Semicon Tech · MOSFETs · TO-252

KND3308A from KIA Semicon Tech, 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 Gate input Gate terminal of the N-channel MOSFET; the datasheet rates gate-source voltage VGSS at +25 V.
2 Drain passive Drain terminal of the N-channel MOSFET; the datasheet rates drain-source voltage VDSS at 80 V.
3 Source passive Source terminal of the N-channel MOSFET; the body diode continuous forward current is rated at 80 A.
