1N5528B-1
1N5518B thru 1N5546B-1
Available on
commercial
versions
Low Voltage Avalanche
500 mW Zener Diodes DO-35
Qualified per MIL-PRF-19500/437
DESCRIPTION
The 1N5518 thru 1N5546 series of 0.5 watt axial-leaded glass Zener Voltage Regulators
provides a selection from 3.3 to 33 volts with tolerances ranging from plus/minus 1% to 20%.
The standard tolerance is plus/minus 5% with the B suffix unless ordered otherwise. These
axial-leaded glass DO-35 Zeners are also available with an internal metallurgical bond option.
This type of bonded Zener package construction is also available in JAN, JANTX, and
JANTXV military qualifications. Microsemi also offers numerous other Zener products to meet
higher and lower power applications.
Qualified Levels:
JAN, JANTX and
JANTXV

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).
Low Regulator (Zener) Current: The lowest rated dc current for the specified power rating.
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
Zener Voltage: The zener voltage the device will exhibit at a specified current (IZ) in its breakdown region.
Voltage Regulation: The change in zener voltage between two specified currents or percentage of IZM.
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.
