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.

NOTE 1: Standard tolerance on JEDEC types shown is +/- 10%. Suffix letter A denotes +/- 5% tolerance; suffix
letter C denotes +/- 2%; and suffix letter D denotes +/- 1% tolerance.
NOTE 2: Voltage measurements to be performed 20 seconds after application of dc test current.
NOTE 3: Zener impedance derived by superimposing on

typical zener Impedance variation with different operating currents.
NOTE 4: Allowance has been made for the increase in
