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.

Zener reference voltage of 6.4 V +/- 5% with tighter
tolerance available at lower voltage
1N4565 thru 1N4584 also have qualification to MIL-
PRF-19500/452 by adding the JAN, JANTX, or
JANTXV prefixes to part numbers a well as the “-1”
suffix; e.g. JANTX1N4574A-1, etc.
0.01%/ºC to 0.0005%/ºC
• Tight reference voltage tolerances available with
nominal value centered at 6.2 V by adding tolerance
1%, 2%, 3%, etc. after the part number for
identification, e.g. 1N4569-2%, 1N4579A-1%,
1N4574A-1-1%, etc.
•
Military surface mount equivalents also available in
DO-213AA by adding UR-1 suffix and the JAN,
JANTX, and JANTXV prefix, e.g.
