DESCRIPTION

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-7 reference diodes are internal-metallurgical-bonded and are 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.

FEATURES

? JEDEC registered 1N4565 thru 1N4584 series .

? 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.
