Four different operating currents are available for selection at 0.5 mA, 1.0 mA, 2.00 mA, and 4.00 mA. These glass axial-leaded DO-35 reference diodes are optionally available with an internal-metallurgical-bond by adding a -1 suffix. This same -1 bonded Zener package construction is also available in JAN, JANTX, and JANTXV military qualifications. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V.

NOTES: 1. When ordering devices with tighter tolerances than specified for the V voltage nominal of 6.2V, add a hyphened suffix to the Z part number for desired tolerance, e.g. 1N4569A-2%, 1N4574A-1-1%, 1N4579-1-2%, 1N4584A-1-3%, etc. o 2. Zener impedance is measured by superimposing 0.75 mA ac rms on 7.5 mA dc 25 C. 3. Voltage measurements to be performed 15 seconds after application of dc current. 4. 1N4565A thru 1N4584A also have qualification to MIL-PRF-19500/452 by adding the JAN, JANTX, JANTXV, or JANS prefixes to part numbers as well as the -1 suffix e.g. JANTX1N4569A-1, JANTXV1N4574A-1, etc. Copyright 2003 Microsemi Page 2 10-27-2003 REV B Scottsdale Division 8700 E.
