KND3403C

KIA Semicon Tech · MOSFETs · TO-252

KND3403C 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; gate-source voltage is rated ±20 V (VGSS, absolute maximum).
2 Drain passive Drain terminal; drain-source voltage is rated 30 V and continuous drain current is rated 80 A at TC = 25 ºC.
3 Source passive Source terminal; the integral reverse P-N junction diode is between drain and source, with continuous source current rated 80 A.
