DESCRIPTION
APPEARANCE
The 1N5221BUR-1 thru 1N5281BUR-1 series of 0.5 watt Zener Voltage
Regulators provides a surface mount equivalent to the popular JEDEC
registered 1N5221B to 1N5281B for 2.4 to 200 volts in a metallurgically
bonded configuration. They are available with standard 5%, 10%, or 20%
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.
DO-213AA
