GLASS SURFACE MOUNT 0.5 WATT
ZENERS
DESCRIPTION
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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
