VOIDLESS HERMETICALLY SEALED
500mW 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 1% and 2% tolerances. They are also available in surface-mount
packages. Microsemi also offers numerous other Zener products to meet higher and lower
power ratings in both thru-hole and surface mount packages.

SYMBOLS & DEFINITIONS
Definition
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK).
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
Maximum Zener Surge Current: The non-repetitive peak value of Zener surge current at a specified wave form.
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
Working Peak Voltage: The maximum peak voltage that can be applied over the operating temperature range. This is
also referred to as Standoff Voltage.
Zener Voltage: The Zener voltage the device will exhibit at a specified current (IZ) in its breakdown region.
Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a
specified rms current modulation (typically 10% of IZT or IZK) and superimposed on IZT or IZK respectively.
