DESCRIPTION
APPEARANCE
The popular 1N746 thru 1N759A series of 0.5 watt Zener Voltage
Regulators provides a selection from 2.4 to 12 volts in standard 5% or 10%
tolerances as well as tighter tolerances identified by different suffix letters
on the part number. The DO-7 packaging option offers a “straight-through”
soldered internal connection with a larger active die element than otherwise
provided in the smaller DO-35 package when needed. It is also available
as a RoHS Compliant option by adding an “e3” suffix.
Microsemi also
offers numerous other Zener products to meet higher and lower power
applications.
