DESCRIPTION
Screening in
reference to
MIL-PRF-19500
available
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.
