MMSZ4690-E3-08 from Vishay Intertech, 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, marked by the cathode bar on the SOD-123 package; for the MMSZ4690 the nominal Zener voltage is 5.6 V (5.32 to 5.88 V) at IZT = 0.05 mA. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; power dissipation is limited to 500 mW (TL = 75 °C) and junction temperature to 150 °C. |
