DESCRIPTION
The popular 1N4565 thru 1N4584A-1 seriesof Zero-TC Reference Diodes providesa selection of both 6.4 V nominal voltages and temperature coefficients to aslow as0.0005%/oC for minimal  voltage change with temperature. Four differentoperating currents are available for selection at 0.5 mA, 1.0 mA, 2.00 mA, and 4.00mA. These glass axial-leaded DO-7 reference diodes are internal-metallurgical-bonded and are also available in JAN, JANTX, and JANTXVmilitary qualifications.  Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages upto 200 V.

FEATURES
•  JEDEC registered 1N4565 thru1N4584series.
•  Reference voltage diodes of nominal 6.4 V +/- 5% with tighter tolerance options available
•  Temperature Coefficient range: 0.01%/oC to 0.0005%/oC.
•  Zener Test Current selection range: 0.500 mA, 1.00 mA, 2.00 mA and 4.00 mA.
•  Internal metallurgical bonded
•  1N4565 thru1N4584 alsohave qualificationto MIL-PRF-19500/452by adding the JAN, JANTX, JANTXV, or JANS prefixes to part numbers a well as the “-1” suffix; e.g. JANTX1N4574A-1, etc.
•  Military surfacemount equivalents also available in DO-213AA by adding UR-1 suffix and the JAN, JANTX, and JANTXV prefix, e.g. JANTX1N4569AUR-1 (seeseparate data sheet)
•  Also available inDO-35 package including military qualifications upto JANTXV (see separate data sheet)

APPLICATIONS/ BENEFITS
