DESCRIPTION
The popular 1N5985BUR-1 t hr u 1N 6 03 1BUR-1 series of 0. 5 watt Zener voltage regulators
provid es a selec tion fr om 2.4 to 200 volts in 1 0%, 5%, 2% and 1% t ol er anc es. These glass
surfac e mount DO-213AA Z eners are als o available in va riou s military equivalent screening
levels by adding a prefix identifier as described in the “part nomenclature” section. Microsemi
als o offers nu merous other Zener products to meet hi gher and lower power applicati ons .

Important: For the latest informat ion, visit our website http://www.microsemi.com.
FEATURES
• Sur face mount equiv alents 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 meta llurgi cal bonds.
• High-reliability screened equivalents in reference to MIL-PRF-19500 are available.
• RoHS compliant versions available (commercial grade only).
APPL ICAT IONS / BENEFITS
• Regulates voltage over a broad operating current and temperature range.
• Extensive sel ection from 2.4 to 200 volts.
• Non-sensitive to ESD (M IL-STD-750, method 1020).
• Minimal capacitance (see Figure 2).
• Inherently radiation hard as desc ribed in Microsemi “Micr oNote 050 ”.

NOTES: 1. Zener impedance is derived from the 1 kHz ac voltage that resul ts when an ac current having an rms value equal to 10% of dc
Zener current (IZT or IZK) is superimposed on IZT or IZK. See “Mi croNote 202 ” for dynamic impedance variation with other
operating currents.
2. Voltage measurements to be performed 20 seconds after application of th e dc test current.
3. The ma xi m um Zener current IZM shown is for the n ominal voltages. The following formula can be used to determine the w orst
c ase current for any toleran ce device:
IZM =
Where VZM is the high end of the voltage toleran ce specified and P is the rated power of the device.
