NCEP1545K

Wuxi NCE Power Semiconductor · MOSFETs · TO-252-2L

NCEP1545K from Wuxi NCE Power Semiconductor, in a TO-252-2L. 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 is limited to ±20 V, with a typical threshold VGS(th) of 3.1 V (2.0 V min, 4.0 V max) at ID=250μA.
2 D passive Drain, the center position and the exposed mounting tab; VDS is rated 150 V and continuous ID is 45 A.
3 S passive Source; continuous body-diode forward current IS is 45 A with VSD of 1.2 V max at IS=20A.
