VOIDLESS HERMETICALLY SEALED 1.5 WATT
GLASS ZENER DIODES
Qualified per MIL-PRF-19500/406
DESCRIPTION
T
his 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.

SYMBOLS & DEFINITIONS
Definition
Zener Voltage: The Zener voltage the device will exhibit at a specified current (I
Z
) in its breakdown region.
Regulator Current: The dc regulator current (I
Z
), at a specified test point (I
ZT
), near breakdown knee (I
ZK
).
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 I
ZT
or I
ZK
) and superimposed on I
ZT
or I
ZK
respectively.
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
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.
