MMSZ4692 from hongjiacheng, in a SOD-123. 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 | K | passive | Cathode end, marked by the cathode line on the body; the zener voltage VZ (6.46 V min, 6.8 V nom, 7.14 V max at IZT = 50 µA) appears here when reverse biased. |
| 2 | A | passive | Anode end, opposite the cathode line; forward voltage VF is 0.9 V at IF = 10 mA. |
