DESCRIPTION
This Zener voltage regulator series is military qualified to MIL-PRF-19500/406 and is ideal for
high-reliability applications where a failure cannot be tolerated. These industry-recognized 1.5
watt Zener voltage regulators are hermetically sealed with void-less glass construction using
an internal metallurgical bond. It includes Zener selections from 3.3 to 200 volts in standard
5% tolerance. 1% and 2% tolerance versions are also available. Microsemi also offers
numerous other Zener products to meet higher and lower power ratings in both thru-hole and
surface mount packages.
