CESDLC3V0J4

Changjing · ESD And Surge Protection (TVS/ESD) · SOT-353

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.
