AZC199-02S from TECH PUBLIC, in a SOT-23. 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 1 (TVS diode anode side); 5V operating voltage, 1.3 pF max capacitance to Pin 3, ±30kV air/contact ESD per IEC 61000-4-2. |
| 2 | I/O2 | passive | Protected line 2 (TVS diode anode side); 5V operating voltage, 1.3 pF max capacitance to Pin 3, ±30kV air/contact ESD per IEC 61000-4-2. |
| 3 | GND | power_in | Common connection of both TVS diodes (ground reference); the datasheet drawing shows it joined to both diodes, and it is not explicitly labelled GND. |
