1N4565 thru 1N4584A-1 DO-35
6.4 Volt Temperature Compensated Zener
Reference Diodes
SCOTTSDALE DIVISION
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%/
o
C 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.

•
JEDEC registered 1N4565 thru 1N4584 series
Internal metallurgical bond option available by
adding a “-1” suffix
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.
Military surface mount equivalents also available in
DO-213AA by adding UR-1 suffix and the JAN,
JANTX, and JANTXV prefix, e.g.
JANTX1N4569AUR-1 (see separate data sheet)
Also available in DO-7 package including military
qualifications up to JANS (see separate data sheet)
JANS equivalent available in DO-35 via SCD
APPLICATIONS / BENEFITS

4.
When ordering devices with tighter tolerances than specified for the V
Z
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.
o
Zener impedance is measured by superimposing 0.75 mA ac rms on 7.5 mA dc @ 25 C.
Voltage measurements to be performed 15 seconds after application of dc current.
