DESCRIPTION
The 1N4678UR-1 thru 1N4717UR-1 series of 0.5 watt glass surface mount
DO-213AA Zener voltage regulators provides a selection from 1.8 to 43 volts
in standard 5% tolerances as well as tighter tolerances with a very low test
current of 50 µA. These have an internal-metallurgical-bond option as
identified with the “-1” suffix. This type of internally bonded Zener package
construction is also available with equivalent military screening as described
in the Features section. Microsemi also offers numerous other Zener
products to meet higher and lower power applications.

FEATURES
•
Surface mount equivalent to JEDEC registered 1N4678
thru 1N4717 series
•
Internal metallurgical bond with the “-1” suffix
•
Options for screening in accordance with MIL-PRF-
19500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, MSP respectively to
part numbers; (e.g. MX1N4678UR-1, MV1N4701UR-1,
MSP1N4709DUR-1, etc.)
•
Nonbonded types also available without the “-1” suffix
for both the axial and surface mount packages
•
DO-7 or DO-35 glass body axial-leaded Zener
equivalents also available per JEDEC registration with
part numbers 1N4678 thru 1N4717 on separate data
sheets
