TPESD0502BA from TECH PUBLIC, in a SOT-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 | I/O1 | passive | Protected line 1 (TVS diode cathode); 5V max reverse working voltage, 0.6pF max to ground, 0.35pF max between I/O pins. |
| 2 | I/O2 | passive | Protected line 2 (TVS diode cathode); 5V max reverse working voltage, 0.6pF max to ground, 0.35pF max between I/O pins. |
| 3 | GND | power_in | Common anode of both TVS diodes, ground reference; ESD rated ±20kV air and ±15kV contact per IEC 61000-4-2. |
