MMSZ4685T1G from onsemi, 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 | Cathode | passive | Cathode terminal, indicated by the polarity band on the package; this is the reverse-biased Zener terminal of the MMSZ4685T1G (3.6 V nominal Zener voltage, 500 mW rating on FR-5 board). |
| 2 | Anode | passive | Anode terminal of the Zener diode, opposite the cathode polarity band; the forward voltage is 0.9 V max at IF = 10 mA per the datasheet. |
