VOIDLESS HERMETICALLY SEALED SURFACE

MOUNT 1.5 WATT GLASS ZENER DIODES

Qualified per MIL-PRF-19500/406

DESCRIPTION

his surface mount, Zener voltage regulator series is military qualified to MIL-PRF-19500/406

Available on

commercial

versions

Qualified Levels:

JAN, JANTX,

JANTXV and JANS

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

) in its breakdown region.

Regulator Current: The dc regulator current (I

), at a specified test point (I

), near breakdown knee (I

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

or I

) and superimposed on I

or I

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.
