VOIDLESS HERMETICALLY SEALED
500mV GLASS ZENER DIODES
Qualified per MIL-PRF-19500/533
DESCRIPTION
This Zener voltage regulator series is military qualified and is ideal for high-reliability
applications where a failure cannot be tolerated. These industry-recognized 0.5 watt Zener
voltage regulators are hermetically sealed with voidless-glass construction using an internal
metallurgical bond. It includes Zener selections from 2.4 to 200 volts in standard 5%
tolerances as well as tighter 1% and 2% tolerances. They are also available in axial leaded
packages. Microsemi also offers numerous other Zener products to meet higher and lower
power ratings in both thru-hole and surface mount packages.
