1N4678-1 thru 1N4717-1

Available on

commercial

versions

500 mW AXIAL-LEADED ZENER DIODES

DESCRIPTION

Screening in

reference to

MIL-PRF-19500

available

The 1N4678-1 thru 1N4717-1 series of 0.5 watt Zener voltage regulators provides a selection

from 1.8 to 43 volts in standard 5% tolerances as well as tighter tolerances. These axial-

leaded glass DO-35 Zeners are available with an internal metallurgical bond similar to military

requirements for similar Zeners. Microsemi also offers numerous other Zener products to

meet higher and lower power applications.
