DESCRIPTION
APPEARANCE
The popular 1N957B thru 1N992B series of 0.5 watt Zener voltage regulators
provides a selection from 6.8 to 200 volts in standard 5% or 10% tolerances
as well as tighter tolerances identified by different suffix letters on the part
number.
The somewhat larger 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. Microsemi
also offers numerous other Zener products to meet higher and lower power
applications.
DO-7
(DO-204AA)

FEATURES
APPLICATIONS / BENEFITS
JEDEC registered 1N957B to 1N992B series
Internal metallurgical bonding equivalent to “-1” suffix
identification on other military DO-7 Zeners
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.
Surface mount equivalents in DO-213AA also
available as MLL957B to MLL992B or with “-1” suffix
(consult factory for other surface mount options)
RoHS Compliant devices available by adding e3 suffix
Smaller DO-35 glass body axial-leaded Zener
equivalents are also available
Regulates voltage over a broad operating current
and temperature range
Extensive selection from 6.8 to 200 V
Standard voltage tolerances are plus/minus 5%
with B suffix, 10 % with A suffix identification
Tight tolerances available in plus or minus 2% or
1% with C or D suffix respectively
Flexible axial-lead mounting terminals
Nonsensitive to ESD
Capacitance also specified (see Figure 3)
Inherently radiation hard as described in
Microsemi MicroNote 050
