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-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)

FEATURES  
APPLICATIONS / BENEFITS  
• JEDEC registered 1N4565 thru 1N4584 series .  
•
Provides minimal voltage change over a broad  
operating temperature range for instrumentation and  
other circuit designs requiring a voltage reference  
• Reference voltage diodes of nominal 6.4 V +/- 5%  
with tighter tolerance options available  
• Temperature Coefficient range: 0.01%/oC to  
•
•
Temperature coefficient selections available from  
0.0005%/oC.  
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.  
Flexible axial-leaded mounting terminals  
Nonsensitive to ESD per MIL-STD-750 Method 1020  
• 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)
