1N746 thru 1N759A, -1, e3 and 1N4370 thru 1N4372A, -1, e3 DO-35 Silicon 500 mW Zener Diodes SCOTTSDALE DIVISION 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 as well as RoHS Compliant by adding an “e3” suffix. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

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 (2mA 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.
