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
