1N4678 thru 1N4717-1 DO-7  
500 mW AXIAL-LEADED ZENER DIODES  
S C O T T S D A L E D I V I S I O N  
DESCRIPTION  
APPEARANCE  
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.  
DO-7  
(DO-204AA)
