These glass axial- leaded DO-35 reference diodes are optionally available with an internal- metallurgical-bond by adding a -1 suffix. This type of 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.

Double Anode electrical specifications apply under both bias polarities. NOTES: 1. Add a -1 suffix for internal metallurgical bond. When ordering devices with tighter tolerances than specified for the V Z voltage nominal of 6.15 V, add a hyphened suffix to the part number for desired tolerance, e.g. 1N827-1-2%, 1N829-1-1%, 1N829A-1%, 1N829A-1-1%, etc. o 2. Zener impedance is measured by superimposing 0.75 mA ac rms on 7.5 mA dc 25 C. 3. The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the specified mV change at any discrete temperature between the established limits. 4. Voltage measurements to be performed 15 seconds after application of dc current. 5. 1N821, 1N823, 1N825, 1N827, and 1N829 also have qualification to MIL-PRF-19500/159 by adding the JAN, JANTX, or JANTXV prefix to part numbers as well as the -1 suffix e.g. JANTX1N827-1, JANTXV1N829-1, etc. Copyright 2003 Microsemi Page 2 10-27-2003 REV C Scottsdale Division 8700 E.
