ZENER DIODES
DESCRIPTION
The popular 1N5221B-1 thru 1N5281B-1 series of 0.5 watt Zener voltage regulators provides a
selection from 2.4 to 200 volts in standard 5% or 10% tolerances as well as tighter tolerances
identified by different suffix letters on the part number. These glass, axial-leaded DO-35
Zeners are also available in various up-screening levels by adding a prefix identifier as
described in the “Part Nomenclature” section of this datasheet. Microsemi also offers
numerous other Zener products to meet higher and lower power applications.
Screening in
reference to
MIL-PRF-19500
available
Important: For the latest information, visit our website http://www.microsemi.com.

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.
Temperature Solder Pad: The maximum solder temperature that can be safely applied to the terminal.
Reverse Voltage: The reverse voltage dc value, no alternating component.
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.
