SEZ52C2V7 from SINO-IC, 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 zener diode; the datasheet's absolute maximum ratings give Ptot 200 mW and storage temperature -55 to +125 ℃ for the device. |
| 2 | Anode | passive | Anode of the zener diode; the datasheet gives a maximum forward voltage of 0.9 V at IF = 10 mA and a surge forward current IFSM of 2.0 A. |
