# CESDLC5V0M5

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-563

CESDLC5V0M5 from TECH PUBLIC, in a SOT-563. 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 I/O line with a TVS diode to GND, rated 5 V max reverse working voltage and 0.5 pF typical capacitance to GND. |
| 2 | GND | power_in | Common ground node of the TVS array, connected directly to the shared diode rail in the schematic; all I/O pins are referenced to it. |
| 3 | I/O2 | passive | ESD-protected I/O line with a TVS diode to GND, rated 5 V max reverse working voltage and 0.5 pF typical capacitance to GND. |
| 4 | I/O3 | passive | ESD-protected I/O line with a TVS diode to GND, rated 5 V max reverse working voltage and 0.5 pF typical capacitance to GND. |
| 5 | I/O4 | passive | ESD-protected I/O line with a TVS diode to GND, rated 5 V max reverse working voltage and 0.5 pF typical capacitance to GND. |
| 6 | I/O5 | passive | ESD-protected I/O line with a TVS diode to GND, rated 5 V max reverse working voltage and 0.5 pF typical capacitance to GND. |
