DESCRIPTION APPEARANCE
The popular 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes
provides a selection of both 6.4 V nominal voltages and temperature
coefficients to as low as 0.0005%/oC for minimal voltage change with
temperature. 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.
DO-35
(DO-204AH)

NOTES:
1. When ordering devices with tighter tolerances than specified for the VZ voltage nominal of 6.2V, add a hyphened suffix to the
part number for desired tolerance, e.g. 1N4569A-2%, 1N4574A-1-1%, 1N4579-1-2%, 1N4584A-1-3%, etc.
2. Zener impedance is measured by superimposing 0.75 mA ac rms on 7.5 mA dc @ 25oC.
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.
