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.
IMPORTANT:

APPEARANCE
DO-213AA
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
APPLICATIONS / BENEFITS
Regulates voltage over a broad operating current and
temperature range
Extensive selection from 1.8 to 43 V
Standard voltage tolerances are plus/minus 5% with
no suffix
Tight tolerances available in plus or minus 2% or 1%
with additional C or D suffix respectively
Hermetically sealed surface mount package
Nonsensitive to ESD per MIL-STD-750 Method 1020
