The UZ5706 Series (and matching UZ5806 Series) are fused‑in‑glass, metallurgically‑bonded 5 W Zener diodes. They feature a small physical size and a surge rating that is twice that of conventional 10 W Zeners. The series is identified by a blue or red cathode band on the body.
The datasheet lists absolute maximum ratings, mechanical dimensions, electrical specifications at 25 °C, temperature operating limits, and JEDEC cross‑reference numbers. It also includes lead temperature derating curves and surge power graphs for proper mounting and usage.
| Zener Voltage Range | 6.8 V to 400 V |
|---|---|
| Surge Rating | 2 × greater than conventional 10 W Zeners |
| Operating Temperature Range | -69 °C to +175 °C |
They can operate and be stored from –69 °C up to +175 °C.
The UZ5706 series has a surge rating that is two times greater than conventional 10 W Zeners.
