MicroNote 050
JEDEC registered 1N746 thru 1N759A and 1N4370
thru 1N4372A series
Internal metallurgical bond option available by adding
a “-1” suffix
Also available in JAN, JANTX, and JANTXV
qualifications per MIL-PRF-19500/127 by adding the
JAN, JANTX, or JANTXV prefixes to part numbers for
desired level of screening as well as –1” suffix; (e.g.
JANTX1N751A-1, JANTXV1N758C-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
MLL746 to MLL759A and MLL4370 to MLL4372A

DESCRIPTION
APPEARANCE
The popular 1N746 thru 1N759A and 1N4370 thru 1N4372A series of 0.5
watt Zener Voltage Regulators provides a selection from 2.4 to 12 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. These are also available in JAN, JANTX, and JANTXV
military qualifications. Microsemi also offers numerous other Zener
products to meet higher and lower power applications.
