APPEARANCE

DO-35

(DO-204AH)

DESCRIPTION

The popular 1N5221 thru 1N5281B series of 0.5 watt Zener Voltage Regulators

provides a selection from 2.4 to 200 volts in standard 5% or 10% tolerances as

well as tighter tolerances identified by different suffix letters on the part number.

These glass axial-leaded DO-35 Zeners are also available in various military

screening levels by adding a prefix identifier as described in the Features

section. Microsemi also offers numerous other Zener products to meet higher

and lower power applications.

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

FEATURES

APPLICATIONS / BENEFITS

•

JEDEC registered 1N5221 to 1N5281B

•

Regulates voltage over a broad operating current

and temperature range

•

Extensive selection from 2.4 to 200 V

Options for screening in accordance with MIL-PRF-

19500 for JAN, JANTX, JANTXV, and JANS are

available by adding MQ, MX, MV, or MSP prefixes

respectively to part numbers with “-1” suffix.

Standard voltage tolerances are plus/minus 5%

with B suffix, 10 % with A suffix identification

•

Tight tolerances available in plus or minus 2% or

1% with C or D suffix respectively

•

Surface mount equivalents available as MLL5221 to

MLL5281B in the DO-213AA MELF style package

including “-1” suffix options (consult factory for others)

•
