The Power'Zeners UZ4706/UZ4806 series are 5 W industrial Zener diodes with a compact glass package and moisture‑impervious construction. They offer a wide voltage range from 6.8 V to 200 V and feature a surge rating that is twice that of comparable plastic‑type devices.
The datasheet lists electrical ratings, mechanical dimensions, and temperature limits, and includes a detailed table of part numbers with corresponding Zener voltage, continuous current, and surge current specifications.
| Zener Voltage Range | 6.8 V to 200 V |
|---|---|
| Storage and Operating Temperature | 65 °C to +175 °C |
| Surge Duration (Test) | 5 ms |
| Surge Current Test Pulse | 8.3 ms peak sinusoidal |
The surge rating is based on a peak sinusoidal pulse of 8.3 ms duration; a square‑pulse rating of 8.3 ms is about 71 % of that value.
The devices are rated for storage and operation from 65 °C up to +175 °C.
The series provides a surge rating that is two times greater than comparable plastic‑type Zeners.
