MMSZ4695 from Changjing, 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 '-', end with the band); positive side in reverse zener operation, with PD 350 mW and TJ/Tstg -55 to +150 ℃. |
| 2 | A | passive | Anode (marked '+', end without the band); forward voltage VF is 0.9 V at IF = 10 mA. |
