CJ3415 R15

Changjing · MOSFETs · SOT-23

CJ3415 R15 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 of the P-channel MOSFET; the datasheet limits gate-source voltage VGS to ±8 V.
2 SOURCE passive Source of the P-channel MOSFET; the datasheet gives no separate pin-level limit for this terminal.
3 DRAIN passive Drain of the P-channel MOSFET; the datasheet rates drain-source voltage VDS at -20 V.
