CESD5V0J4 from Leiditech, 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 | Protected line, connected to the lower steering diode of the left channel in the pin configuration drawing; part is rated for 5V reverse working voltage and ±30kV air / ±25kV contact ESD per IEC 61000-4-2. |
| 2 | GND | power_in | Common node of the diode array, where the middle node of both channels joins in the pin configuration drawing; reference or ground connection for the ESD protection. |
| 3 | I/O2 | passive | Protected line, connected to the lower steering diode of the right channel in the pin configuration drawing; part is rated for 5V reverse working voltage and ±30kV air / ±25kV contact ESD per IEC 61000-4-2. |
| 4 | I/O3 | passive | Protected line, connected to the upper Zener diode of the right channel in the pin configuration drawing; part is rated for 5V reverse working voltage and ±30kV air / ±25kV contact ESD per IEC 61000-4-2. |
| 5 | I/O4 | passive | Protected line, connected to the upper Zener diode of the left channel in the pin configuration drawing; part is rated for 5V reverse working voltage and ±30kV air / ±25kV contact ESD per IEC 61000-4-2. |
