DESCRIPTION
APPEARANCE
The 1N5221BUR thru 1N5281BUR 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 standard 5%
tolerances as well as tighter tolerances identified by different suffix letters on
the part number.
These are also available with an internal-metallurgical-
bond option by adding a “-1” suffix (see separate data sheet). Microsemi
also offers numerous other Zener products to meet higher and lower power
applications.
DO-213AA
