DESCRIPTION
APPEARANCE
DO-7
The popular 1N746 thru 1N759A 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. The 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. It is also available
as a RoHS Compliant option by adding an “e3” suffix. Microsemi also
offers numerous other Zener products to meet higher and lower power
applications.

* JEDEC Registered Data
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 IZT, a 60 cps, rms ac current equal to 10% IZT (2 mA ac). See MicroNote 202 for
typical zener Impedance variation with different operating currents.
NOTE 4: Allowance has been made for the increase in VZ due to ZZ and for the increase in junction temperature as the unit approaches
thermal equilibrium at the power dissipation of 400 mW.
