TECH PUBLIC · ESD Protection Devices · SOD-523
TPAZ5125-01H 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 | Terminal 1 (bidirectional TVS) | passive | One terminal of the bidirectional TVS diode, shown as pin 1 in the pin configuration diagram; the device has a 5 V reverse working voltage (VRWM), a 6.5 V typical breakdown voltage, and ±30 kV IEC 61000-4-2 air and contact ESD rating. |
| 2 | Terminal 2 (bidirectional TVS) | passive | The other terminal of the bidirectional TVS diode, shown as pin 2 in the pin configuration diagram; the device has a 5 V reverse working voltage (VRWM), a 6.5 V typical breakdown voltage, and ±30 kV IEC 61000-4-2 air and contact ESD rating. |
