1N957B thru 1N992B, e3 DO-7
Silicon 500 mW Zener Diodes
SCOTTSDALE DIVISION
DESCRIPTION
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.

FEATURES
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
APPLICATIONS / BENEFITS
