MMSZ5235ET1G 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, marked by the polarity band on the package; for the MMSZ5235ET1G the nominal Zener voltage is 6.8 V (min 6.46 V, max 7.14 V) at IZT = 20 mA. |
| 2 | Anode | passive | Anode terminal of the Zener diode, opposite the cathode polarity band; the device is rated for 500 mW on FR-4 or FR-5 board and a junction and storage temperature range of -55 °C to +150 °C. |
