DESCRIPTION
APPEARANCE
The 1N5728 thru 1N5757 series of 0.5 watt Zener Voltage Regulators
provides a selection from 4.7 to 75 volts in standard 5% tolerances as well
as tighter tolerances identified by a “C” or “D” suffix letter on the part
number. These glass axial-leaded DO-35 Zeners are also available with an
internal-metallurgical-bond option by adding a “-1” suffix. Microsemi also
offers numerous other Zener products to meet higher and lower power
applications.
