DESCRIPTION

APPEARANCE

DO-7

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.

(DO-204AA)
