CJU40P04A

Changjing · MOSFETs · TO-252-2L

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.
