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.

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”.
