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. These glass axial-leaded DO-35 Zeners are
also available with an internal-metallurgical-bond option by adding a “-1”
suffix. The 1N962B-1 thru 1N992B-1 are available in JAN, JANTX, and
JANTXV military qualifications.
Microsemi also offers numerous other
Zener products to meet higher and lower power applications.
DO-35
(DO-204AH)

FEATURES
APPLICATIONS / BENEFITS
JEDEC registered 1N957B(-1) to 1N992B(-1) series
Internal metallurgical bond option available by
adding a “-1” suffix
Also available in JAN, JANTX, and JANTXV
qualifications per MIL-PRF-19500/117 by adding the
JAN, JANTX, or JANTXV prefixes to part numbers
for desired level of screening as well as “-1” suffix;
(e.g. JANTX1N962B-1, JANTXV1N986C-1, etc.)
Military Surface Mount equivalents also available in
DO-213AA by adding a UR-1 suffix in addition to the
JAN, JANTX, and JANTXV prefix; e.g.
JANTX1N962BUR-1 (see separate data sheet)
Commercial Surface Mount equivalents available as
MLL957B to MLL992B or with “-1” suffix for bonded
in the DO-213AA MELF style package (consult
factory for others)
DO-7 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
