Changjing · MOSFETs · TO-252-2L
CJU40P03 from Changjing, 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 limited to ±20V (VGS rating, IGSS tested at VGS=±20V), threshold VGS(th) -1V to -2.5V at ID=-250µA. |
| 2 | D | passive | Drain (center position and mounting tab); drain-source voltage -30V minimum breakdown at ID=-250µA, continuous drain current -40A. |
| 3 | S | passive | Source; drain-source diode continuous forward current IS of -40A and pulsed ISM of -160A. |
