CJ2305

Changjing · MOSFETs · SOT-23

CJ2305 from Changjing, in a SOT-23. 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; the datasheet limits gate-source voltage VGS to ±8 V.
2 SOURCE passive Source terminal of the P-channel MOSFET; the datasheet rates the source-drain diode continuous current IS at -0.8 A.
3 DRAIN passive Drain terminal of the P-channel MOSFET; the device is rated for drain-source voltage VDS of -12 V and continuous drain current ID of -4.1 A.
