Description

The popular the 1N746-1 of 0.5 watt Zener Voltage Regulators provides a selection from 2.4 to 12 volts in standard 5% or 10% tolerances as wel as tighter tolerances identified by different suffix letters on the part number.  These glass axial-leaded DO-35 Zeners of the 1N746-1 are also available with an internal-metallurgical-bond option by adding a "-1" suffix.  These are also available in JAN, JANTX, and JANTXV military qualif
cations.  Microsemi also offers numerous other Zener productsto meet higher and lower power applications.
