DESCRIPTION 
APPEARANCE 
The 1N4099UR thru 1N4135UR and 1N4614UR thru 1N4627UR series of 
0.5 watt glass surface mount DO-213AA Zener voltage regulators provides 
a selection from 1.8 to 100 volts in standard 5% tolerances as well as 
tighter tolerances identified by different suffix letters on the part number.  
These are also available with an internal-metallurgical-bond option by 
adding a “-1” suffix (see separate data sheet) including JAN, JANTX, and 
JANTXV military qualifications.  Microsemi also offers numerous other 
Zener products to meet higher and lower power applications.
