The MMSZ4684 is a half watt, general purpose, medium current surface mount Zener in the SOD-123 package. The SOD-123 package has the same footprint as the glass mini-melf (LL-34) package & provides a convenient alternative to the Leadless package.
The MMSZ4684 is a half‑watt, general‑purpose, medium‑current Zener diode offered in an SOD‑123 surface‑mount package. It features a compact footprint compatible with the glass mini‑melf (LL‑34) package and includes a Class 3 ESD rating (>16 kV) for robust handling.
The document lists absolute maximum ratings, electrical characteristics such as Zener voltage, leakage and forward voltage, as well as thermal resistance values and detailed package dimensions. Ordering information and a disclaimer regarding life‑support usage are also provided.
| Reverse Leakage (IR) at VR = 1.5 V | 7.5 µA |
|---|---|
| Forward Voltage (VF) at IF = 10 mA | 900 mV |
| Storage Temperature (TSTG) | -55 °C to 150 °C |
| Thermal Resistance Junction‑to‑Ambient (RQJA) | 340 °C/W |
| Package dimension A (length) | 1.400 mm |
The diode can be stored from –55 °C up to 150 °C.
The forward voltage is 900 mV when 10 mA flows through the diode.
