# MMSZ4702-E3-08

**Vishay Intertech** · Zener Diodes · SOD-123

MMSZ4702-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 | CATHODE | passive | Cathode terminal, identified by the cathode bar on the SOD-123 outline; the MMSZ4702 nominal Zener voltage is 15 V (VZ 14.3 V min to 15.8 V max at IZT 0.05 mA). |
| 2 | A | passive | Anode terminal of the Zener diode; the datasheet gives a maximum forward voltage of 0.9 V at IF = 10 mA. |
