AZ5125-01H-ES from ElecSuper, 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 | IO1 | bidirectional | Connects to the protected bi-directional I/O line; the device has a 5.0 V peak reverse working voltage (VRWM) and is rated for ±25 kV IEC 61000-4-2 contact and air discharge. |
| 2 | IO2 | bidirectional | Connects to the other side of the protected bi-directional I/O line (I/O to I/O junction capacitance 15 pF typ., 20 pF max. at VR = 0 V, f = 1 MHz); the datasheet gives no separate per-pin limits. |
