ESD5V0U05-523 from TECH PUBLIC, in a SOD-523. 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 | Cathode | passive | Cathode of the unidirectional TVS diode, connected to the protected signal line; reverse working voltage 5 V max, breakdown 6.5 V min to 9.0 V max at 1 mA. |
| 2 | Anode | passive | Anode of the unidirectional TVS diode, normally connected to ground; the datasheet gives ±30 kV ESD (air and contact) per IEC 61000-4-2. |
