KCD2908A

KIA Semicon Tech · MOSFETs · TO-252

KCD2908A from KIA Semicon Tech, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Gate input Gate terminal of the N-channel MOSFET. Controls channel conduction via VGS; threshold voltage VGS(th) = 2.0-4.0 V (typ 3.0 V), absolute maximum VGS = ±20 V. Typical drive is VGS = 10 V for full enhancement (RDS(on) typ 4.3 mΩ).
2 Drain passive Drain terminal of the N-channel MOSFET, also connected to the TO-252 tab. Drain-to-source breakdown voltage BVDSS = 85 V min; continuous ID = 110 A at TC=25 °C (TO-252); pulsed IDP = 480 A. Body diode anode is Source, cathode is Drain (VSD typ 0.85 V @ 40 A).
3 Source passive Source terminal of the N-channel MOSFET and reference for VGS. Carries the drain current back to the load return; also forms the anode of the intrinsic body diode (reverse recovery time trr typ 68 ns, Qrr typ 260 nC).
