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.

FEATURES

• 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.
• Surface mount equivalents available as MLL5221 to
   MLL5281B in the DO-213AA MELF style package
