KCB2904A

KIA Semicon Tech · MOSFETs · TO-263

KCB2904A from KIA Semicon Tech, in a TO-263. 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 SGT MOSFET, rated for VGS of ±20 V per the absolute maximum ratings.
2 Drain passive Drain terminal of the N-channel SGT MOSFET, rated for VDS of 45 V per the absolute maximum ratings.
3 Source passive Source terminal of the N-channel SGT MOSFET, serving as the return path for the drain current.
