CJ2302S

Changjing · MOSFETs · SOT-23

CJ2302S 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	MOSFET gate terminal; the gate-source voltage is rated VGS ±8 V in the maximum ratings.
2	SOURCE	passive	MOSFET source terminal; the continuous source-drain diode conduction current is rated IS 0.6 A.
3	DRAIN	passive	MOSFET drain terminal; the drain-source voltage is rated VDS 20 V, with continuous drain current ID 2.1 A at TJ=150℃.
