CJ2301 S1

Changjing · MOSFETs · SOT-23

CJ2301 S1 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 TrenchFET; gate-source voltage is limited to ±8 V (VGS).
2 SOURCE passive Source terminal; continuous source-drain diode current is limited to -0.72 A (IS) in the maximum ratings.
3 DRAIN passive Drain terminal; drain-source voltage is rated -20 V (VDS) with continuous drain current of -2.3 A (ID) at Ta=25℃.
