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.

(DO-204AA)

* 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 I_ZT, a 60 cps, rms ac current equal to 10% I_ZT(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 V_Zdue to Z_Zand for the increase in junction temperature as the unit approaches

thermal equilibrium at the power dissipation of 400 mW.
