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%/
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-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.
DO-7
(DO-204AA)

Zener Test Current selection range: 0.500 mA, 1.00
mA, 2.00 mA and 4.00 mA.
Internal metallurgical bonded
1N4565 thru 1N4584 also have qualification to MIL-
PRF-19500/452 by adding the JAN, JANTX,
JANTXV, or JANS 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-35 package including military
qualifications up to JANTXV (see separate data
sheet)

APPLICATIONS / BENEFITS
Provides minimal voltage change over a broad
operating temperature range for instrumentation and
other circuit designs requiring a voltage reference
Temperature coefficient selections available from
0.01%/oC to 0.0005%/oC
Tight reference voltage tolerances available with
nominal value of 6.4 V by adding tolerance 1%, 2%,
3%, etc. after the part number for identification, e.g.
1N4569-2%, 1N4579A-1%, 1N4574A-1-1%, etc.
