USHA Z4 Datasheet
Voltage Regulator Diode
R
;
Zener 47 V / 10 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
• Hermatic metal glass seal .
• Anode to case
• Tvj max = 175 °C
10 W [Tcase = 75 °C ]
