1N5221UR-1 thru 1N5281BUR-1,e3

(or MLL5221-1 thru MLL5281B-1,e3)

METALLURGICALLY BONDED GLASS

SURFACE MOUNT 500 mW ZENERS

S C O T T S D A L E D I V I S I O N

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

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
