Changjing · MOSFETs · SOT-23
CJ8810 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, with ESD protection on the gate; gate-source voltage VGS is rated ±12 V. |
| 2 | SOURCE | passive | Source of the N-channel MOSFET; the datasheet gives no separate pin-level limit beyond the device maximum ratings. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET; drain-source voltage VDS is rated 20 V and continuous drain current ID is 7 A at Ta=25℃. |
