CESD5V0K5

Changjing · ESD And Surge Protection (TVS/ESD) · SOT-363

CESD5V0K5 from Changjing, in a SOT-363. 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 TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A); pin 1 is marked by the solid dot.
2 GND power_in Common ground/anode node of all five protection diodes; ESD ratings are specified per channel from I/O to GND.
3 I/O2 passive ESD-protected line 2 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A).
4 I/O3 passive ESD-protected line 3 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A).
5 I/O4 passive ESD-protected line 4 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A).
6 I/O5 passive ESD-protected line 5 (uni-directional TVS to GND, VRWM 5 V, clamping 12 V max at IPP=5 A).
