Changjing · MOSFETs · SOT-23
CJ3404 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 N-channel MOSFET; the datasheet gives the gate-source voltage rating as VGS ±20 V. |
| 2 | SOURCE | passive | Source terminal; the source leads are separated so a Kelvin connection can bypass source inductance, and the device is rated VDS 30 V with ID 5.8 A (t ≤ 10 s). |
| 3 | DRAIN | passive | Drain terminal; the device is rated for drain-source voltage VDS 30 V, continuous drain current 5.8 A (t ≤ 10 s) and pulsed drain current 30 A. |
