Surface Mount 500 mW Zener Diodes
DESCRIPTION
The popular 1N5985BUR-1 thru 1N6031BUR-1 series of 0.5 watt Zener voltage regulators
provides a selection from 2.4 to 200 volts in 10%, 5%, 2% and 1% tolerances. These glass
surface mount DO-213AA Zeners are also available in various military equivalent screening
levels by adding a prefix identifier as described in the “part nomenclature” section. Microsemi
also offers numerous other Zener products to meet higher and lower power applications.
Important: For the latest information, visit our website http://www.microsemi.com.
FEATURES
Surface mount equivalents to JEDEC registered 1N5985 to 1N6031 series.
Similar to operating current conditions of the BZX55 Pro Electron series of Zener products in
Europe.
Multiple voltage tolerances are available (see part nomenclature).
Internal metallurgical bonds.
High-reliability screened equivalents in reference to MIL-PRF-19500 are available.
RoHS compliant versions available (commercial grade only).
APPLICATIONS / BENEFITS
Regulates voltage over a broad operating current and temperature range.
Extensive selection from 2.4 to 200 volts.
Non-sensitive to ESD (MIL-STD-750, method 1020).
Minimal capacitance (see Figure 2).
Inherently radiation hard as described in Microsemi “MicroNote 050”.

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 Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
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.
