Voltage Regulator Diode

Usha Ltd  

Voltage Regulator Diode

Zener 82 V / 50 W

Technical Data

Typical applications : Designed to provide a near constant voltage when

operated in the reverse breakdown mode but when operated with a forward bias

it behaves similarly to any forward biased rectifier junction.

Features :

• Ptot 50 W [Tcase = 75 °C ]

• Hermatic metal glass seal .

• Anode to case

• Tvj max = 175 °C
