VOIDLESS HERMETI CALLY SEALED
500mV GLASS ZENER DIODES
Qualified per MIL-PRF-19500/533
Quali f i ed Lev els:
JAN, J AN TX, JAN TXV
and JANS
Thi s Zener voltage regu lat or series is military qualified and is ideal for high-reliability
applications wher e a fail ure cannot be t olerated. Thes e i ndu stry-r ecognized 0.5 watt Zener
voltage regulators are hermet i cally sealed with void less -glass con st ruction using an internal
metallu r gical bond . It includes Zener selec tions from 2.4 to 200 volts in s tandard 5%
t ol er anc es as well as 1% and 2% tolerances . They are also available in su r face-mount
pack ages. Microsemi al so offers numerous oth er Zener product s to m eet higher an d lower
po wer ra ti ngs i n bo th t hru-hole and surface mount packag es.
