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)  
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com  
FEATURES  
APPLICATIONS / BENEFITS  
• JEDEC registered 1N746 thru 1N759A series  
• Internally solder bonded  
• Options for screening in accordance with MIL-PRF-  
19500 for JAN, JANTX, JANTXV, and JANS are  
available by adding MQ, MX, MV, or MSP prefixes  
respectively to part numbers.  
•
Regulates voltage over a broad operating current  
and temperature range  
•
•
