1N4565A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4565A/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.01%/°C. It operates at a test current (IZT) of 0.5 mA, features a maximum reverse leakage current of 2 µA at 3 V, and has a dynamic impedance of 200 Ω. The device is housed in a DO-7 (DO-204AA) glass axial-leaded package and supports tape-and-reel packaging via the TR suffix.

Single Zener Diodes Feature Summary

• Temperature-compensated design for minimal voltage change over broad operating ranges
• Internal metallurgical bonding for structural integrity
• ESD non-sensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low temperature drift
• Military qualification applications (with JAN/JANTX prefixes)

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as datasheets indicate Microsemi Scottsdale Division while distributors list Microchip Technology. Confirm that the TR suffix correctly denotes tape-and-reel packaging per EIA-296 standards. Ensure the component meets the required JEDEC registration and tolerance specifications for the intended circuit application.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.01%/°C temperature coefficient is required. The 0.5 mA test current suits low-power applications. Verify compatibility with the DO-7 through-hole package and ensure the operating environment stays within the specified -65°C to +175°C range.

Single Zener Diodes Part Context

This part belongs to the 1N4565 thru 1N4584A-1 series of zero-TC reference diodes. These devices are available in various operating currents (0.5 mA to 4.0 mA) and tighter tolerance options. Military qualifications are available by adding JAN, JANTX, or JANTXV prefixes.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N4565 series variants with different temperature coefficients or test currents. Verify pinout and package dimensions (DO-7/DO-204AA) match the existing footprint before substitution.

Single Zener Diodes FAQ

What is the maximum temperature coefficient for the 1N4565A?

The maximum temperature coefficient is 0.01%/°C.

Does the TR suffix affect the electrical function?

No, the TR suffix only indicates tape-and-reel packaging per EIA-296 standards; it does not change the electrical characteristics.
