1N4678 thru 1N4717-1 DO-7
500 mW AXIAL-LEADED ZENER DIODES
DESCRIPTION
The 1N4678 thru 1N4717 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 identified by different suffix letters on the part number.
These glass axial-leaded DO-7 Zeners also have an internal-metallurgical-
bond similar to other military requirements for these packages. Microsemi
also offers numerous other Zener products to meet higher and lower power
applications.
APPEARANCE
DO-7
(DO-204AA)
