CJ3406 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 N-channel MOSFET; the datasheet gives VGS(th) of 1 to 3 V at VDS = VGS and ID = 250 µA and a absolute gate-source voltage rating of ±20 V. |
| 2 | SOURCE | passive | Source of the N-channel MOSFET; the device is rated for a drain-source voltage VDS of 30 V and a continuous drain current ID of 3.6 A. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET; the device is rated for a pulsed drain current IDM of 15 A and a power dissipation PD of 0.35 W. |
