ESD5Z12 from YFW, 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 ESD5Z12 TVS diode, marked as pin 1 in the simplified SOD-523 outline; the device has a working peak reverse voltage (VRWM) of 12.0 V max and a breakdown voltage (VBR) of 13.3 V min at IT = 1 mA. |
| 2 | Anode | passive | Anode of the ESD5Z12 TVS diode, marked as pin 2 in the simplified SOD-523 outline; the maximum reverse leakage current is 1.0 µA at VRWM = 5 V. |
