CESDLC5V0K5

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

CESDLC5V0K5 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 at the bottom of the schematic, with a uni-directional TVS to the common node; VRWM 5V, clamping 13V at IPP=2.5A (8/20µs), CJ 10pF typ at VR=0V, 1MHz.
2 GND power_in Common ground/reference node of the array, to which all protected I/O lines clamp; ESD ratings are per channel (I/O to GND).
3 I/O2 passive ESD-protected line at the bottom of the schematic, with a uni-directional TVS to the common node; VRWM 5V, clamping 13V at IPP=2.5A (8/20µs), CJ 10pF typ at VR=0V, 1MHz.
4 I/O3 passive ESD-protected line at the top of the schematic, with a uni-directional TVS to the common node; VRWM 5V, clamping 13V at IPP=2.5A (8/20µs), CJ 10pF typ at VR=0V, 1MHz.
5 I/O4 passive ESD-protected line at the top of the schematic, with a uni-directional TVS to the common node; VRWM 5V, clamping 13V at IPP=2.5A (8/20µs), CJ 10pF typ at VR=0V, 1MHz.
6 I/O5 passive ESD-protected line at the top of the schematic, with a uni-directional TVS to the common node; VRWM 5V, clamping 13V at IPP=2.5A (8/20µs), CJ 10pF typ at VR=0V, 1MHz.
