DESCRIPTION APPEARANCE
The popular 1N746 thru 1N759A and 1N4370 thru 1N4372A series of 0.5
DO-35
watt Zener Voltage Regulators provides a selection from 2.4 to 12 volts in
(DO-204AH)
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 as well as RoHS Compliant by adding an e3 suffix.
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 I , a 60 cps, rms ac current equal to 10% I (2mA ac). See MicroNote 202 for
