DESCRIPTION
The popular 1N957BUR-1 through 1N992BUR-1 series of 0.5 watt Zener voltage regulators provides a selection from 6.8 to 200 volts in a standard 5%, 2% and 1% tolerance versions. These glass MELF DO-213AA Zeners feature an internal metallurgical bond and are available in military qualified and commercial RoHS compliant versions. Military qualified versions are available on the 1N962BUR-1 through 1N992BUR-1 range of part numbers.

FEATURES
• JEDEC registered 1N957B to 1N992B number series.
• Internal metallurgical bond.
• *JAN, JANTX, and JANTXV qualifications are available per MIL-PRF-19500/117 for part numbers 1N962BUR-1 through 1N992BUR-1.
• Upscreening is available in reference to MIL-PRF-19500 for the range of 1N957BUR-1 through 1N961BUR-1. (See part nomenclature for all available options.)
• RoHS compliant versions available (commercial grade only).

APPLICATIONS / BENEFITS
• Regulates voltage over a broad operating current and temperature range.
• Extensive selection from 6.8 to 200 V.
• Standard voltage tolerance is ± 5% with optional tighter tolerances of ± 2% or 1%.
• Small size for high density mounting using the surface mount method (see package illustration).
• Non-sensitive to ESD per MIL-STD-750 method 1020.
• Minimal capacitance.
• Inherently radiation hard as described in Microsemi MicroNote 050.
