MMSZ4703T1G 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 of the Zener diode, marked by the polarity band on the SOD-123 package; the MMSZ4703T1G has a nominal Zener voltage of 16 V (15.20 V min, 16.80 V max) measured at IZT = 50 µA. |
| 2 | Anode | passive | Anode of the Zener diode, opposite the cathode band; the device is a Zener voltage regulator rated 500 mW on FR-4 or FR-5 board. |
