USHA Z11 Datasheet

Voltage Regulator Diode
Zener 62 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 :

• P
