DESCRIPTION

APPEARANCE

DO-35

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

(DO-204AH)

military qualifications.

Microsemi also offers numerous other Zener

products to meet higher and lower power applications.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

* 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(2mA 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.
