USHA Z12 Datasheet
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 :
• P
