1. Product Overview:

️· Type: 6.4 Volt Temperature Compensated Zener Reference Diodes
️· Part Numbers: 1N4565 through 1N4584A
️· Function: Designed for use as a stable voltage reference in circuits. They are specifically engineered to have a relatively constant voltage output over a range of temperatures.
️· Package: DO-7 (a common through-hole metal case package).

2. Key Features:

️· Stable Voltage Reference: Provides a stable 6.4V output.
️· Temperature Compensation: Minimizes the change in voltage with temperature variations.
️· Military Qualification: Available with military qualification to MIL-PRF-19500/452 (using prefixes like JAN, JANTX, JANTXV, or JANS).
️· Radiation Hardened Option: Designated with an "RH" prefix (e.g., RH4584A) for applications requiring resistance to radiation effects.

3. Electrical Specifications (Typical Values at 25°C unless otherwise noted):

*(See Table on Page 1 of the datasheet. Key parameters are summarized below. Values vary slightly for each part number from 4000 to 400mA. Please refer to the datasheet for complete details)*

️· Zener Voltage (Vz): 6.4V (nominal)
️· Temperature Coefficient: Listed in the Table, values generally vary from -0.034 to -0.039 %.
️· Test Current (IZ): Varies from 400mA to 400mA depending on the part number.
️· Zener Impedance: Measured with a superimposed AC signal (0.75mA RMS on 7.5mA DC).
️· Reverse Breakdown Voltage: 6.4 V
️· Forward Voltage: Typically less than 1.2V
️· Reverse Leakage Current: Typically less than 10 uA
️· Forward Current: Ranges from 400mA - 400mA.

4. Ordering Information and Options:

️· Standard Parts: 1N4565 – 1N4584A (Commercial grade)
️· Military Grade: Add prefixes like JAN, JANTX, JANTXV, or JANS, along with a "-1" suffix. Example: `JANTX1N4569A-1`
️· Radiation Hardened: Use "RH" prefix instead of "1N". Example: `RH4584A`
️· Tighter Tolerance: Add a hyphen followed by the desired tolerance percentage to the part number (e.g., `1N4569A-2%`).

5. Important Notes:

️· Datasheet is Critical: Always consult the full datasheet for complete specifications, graphs of typical performance, and detailed information on testing conditions.
️· Graphs: The datasheet includes graphs that show the typical change in temperature coefficient and change in Zener voltage with changes in operating current. These are important for understanding the device's behavior in different applications.
️· Military Qualification: If military qualification is required, be sure to specify the correct prefix and suffix when ordering.
