CESDLC3V0J4 from Changjing, in a SOT-353. 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 | I/O1 | passive | ESD-protected line 1 (uni-directional channel, I/O to GND), 3V reverse stand-off, 9 pF typical capacitance. |
| 2 | GND | power_in | Common ground reference for all four protected channels (ESD ratings are specified per channel I/O to GND). |
| 3 | I/O2 | passive | ESD-protected line 2 (uni-directional channel, I/O to GND), 3V reverse stand-off, 9 pF typical capacitance. |
| 4 | I/O3 | passive | ESD-protected line 3 (uni-directional channel, I/O to GND), 3V reverse stand-off, 9 pF typical capacitance. |
| 5 | I/O4 | passive | ESD-protected line 4 (uni-directional channel, I/O to GND), 3V reverse stand-off, 9 pF typical capacitance. |
