CS2N65A5

SEP · MOSFETs · TO-252

CS2N65A5 from SEP, 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 G input Gate; gate-source voltage rated ±30 V, threshold VGS(th) 2 V min to 4 V max at ID = 250 µA.
2 D passive Drain (center lead is trimmed on TO-252, drain connects via the mounting tab); VDS rated 650 V and continuous ID 2 A.
3 S passive Source; body-diode continuous current IS up to 2 A and pulsed 8 A.
