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. |
