The Microsemi 3EZ series Zener diodes are offered in a molded axial‑lead package with ratings from 3.9 V to 200 V Zener voltage. Key features include a 3 W power dissipation capability, high surge current rating, and a typical forward voltage of 1.2 V at 200 mA.
Maximum ratings specify a junction and storage temperature range of –65 °C to +175 °C, a power derating of 2 mW/°C above 25 °C, and detailed electrical characteristics such as dynamic impedance (0.032 ~ 0.002 Ω) and Zener voltage measurement procedures. Mechanical data note a weight of about 0.4 g and lead placement 3/8"–1/2" from the mounting clips.
| Zener Voltage Range | 3.9 V to 200 V |
|---|---|
| Junction and Storage Temperature | -65 °C to +175 °C |
| Forward Voltage @ 200 mA | 1.2 V |
| Power Derating | 2 mW/°C above 25 °C |
| Typical Weight | 0.4 g |
The 3EZ series covers Zener voltages from 3.9 V up to 200 V.
They are rated for junction and storage temperatures from –65 °C to +175 °C.
The Zener voltage is measured by applying a test current of 40 µA plus 10 µA before reading.
