1N4567AE3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4567AE3/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.002 %/°C. It operates at a test current of 0.5 mA, features a maximum reverse current of 2 µA at 3 V, and has a dynamic impedance of 200 Ohms. The device is housed in a DO-7 (DO-204AA) glass axial-leaded package with an internal metallurgical bond. It supports tape and reel packaging via the TR suffix and operates within a temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad operating ranges
• Internal metallurgical bonded construction for stability
• Hermetically sealed glass case with flexible axial-leaded terminals

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low temperature drift
• Military and aerospace applications qualifying under MIL-PRF-19500/452

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application, as the 'TR' indicates tape and reel packaging while other suffixes may denote military qualifications or tighter tolerances. Confirm that the DO-7 package dimensions align with your board layout constraints. Ensure the operating current remains within specified limits to maintain optimal voltage-temperature stability during procurement planning.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.002 %/°C temperature coefficient is required. Consider the 0.5 mA test current specification for power dissipation calculations. Verify compatibility with existing circuit biasing networks. Evaluate the DO-7 package against available mounting space. Check if military qualification prefixes are necessary for environmental resilience.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microsemi (now Microchip Technology). The series offers various temperature coefficients and operating currents to suit different precision requirements. These diodes are JEDEC registered and provide a reliable solution for applications needing stable voltage references across wide temperature ranges.

Single Zener Diodes Replacement Considerations

Direct replacements include other parts from the 1N4565-1N4584A-1 series with matching electrical characteristics. Verify equivalent temperature coefficients and test currents. Military equivalents may require JAN, JANTX, or JANTXV prefixes. Surface mount alternatives exist in the DO-213AA package with UR-1 suffixes.
