CJU40P04A 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 | GATE | input | Gate terminal of the P-channel MOSFET; gate-source voltage is limited to ±20 V. |
| 2 | DRAIN | passive | Drain terminal of the MOSFET; rated for a drain-source voltage of -40 V and a continuous drain current of -40 A. |
| 3 | SOURCE | passive | Source terminal of the MOSFET, referenced for the -40 V drain-source rating and the ±20 V gate-source limit. |
