DESCRIPTION
The 1N5221BUR-1 thru 1N5281BUR-1 series of 0.5 watt Zener voltage regulators provides a surface mount equivalent to the popular JEDEC registered 1N5221 to 1N5281 series for 2.4 to 200 volts in a metallurgically bonded configuration. They are available with standard 5% or 10% tolerances as well as tighter tolerances identified by different suffix letters on the part number. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

FEATURES
• Surface mount equivalent of JEDEC registered 1N5221 thru 1N5281 series.
• Voltage tolerances of 10%, 5%, 2%, and 1% available.
• Hermetically sealed surface mount package.
• Internal metallurgical bond.
• Up-screening in reference to MIL-PRF-19500 is available. (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 2.4 to 200 V.
• Non-sensitive to ESD (MIL-STD-750 method 1020).
• Minimal capacitance (see Figure 3).
• Inherently radiation hard per Microsemi “MicroNote 050”.
