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. Also available in: DO-35 (DO-204AH) (axial-leaded) 1N5221B-1 thru 1N5281B-1 Important: For the latest information, visit our website http://www.microsemi.com.

Devices with guaranteed limits on all six parameters are indicated by suffix “A” for +/- 10%, “B” for +/- 5%, “C” for +/- 2%, and “D” for +/- 1% tolerance. NOTE 2: The electrical characteristics are measured after allowing the device to stabilize for 20 seconds. NOTE 3: Temperature coefficient (αvz). Test conditions for temperature coefficient are as follows: a. IZT = 20 mA, T1 = 25 oC, T2 = 125 oC (1N5221AUR-1 & BUR-1 thru 1N5242AUR-1 & BUR-1) b. IZT = Rated IZT, T1 = 25 oC, T2 = 125 oC (1N5243AUR-1 & BUR-1 thru 1N5281AUR-1 & BUR-1) Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.
