1N4566A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4566A-1/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a tight tolerance of ±0.5%. It operates at a test current of 0.5 mA and features an internal metallurgical bond for enhanced reliability. The device is housed in a DO-35 (DO-204AH) axial leaded package, suitable for through-hole mounting. It offers a maximum power dissipation of 500 mW and maintains stability across a wide operating temperature range from -55°C to +100°C.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over temperature
• Internal metallurgical bond construction for high reliability
• Tight voltage tolerance of ±0.5% at 6.4 V nominal

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature compensated oscillator references
• High-stability analog signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets, as variations exist within the series. Confirm availability status, as some listings indicate discontinued or restricted supply conditions. Ensure the selected variant matches the required military or commercial qualification levels if applicable to the design constraints.

Single Zener Diodes Selection Notes

Select this component when precise voltage stability over temperature is critical. The 6.4 V nominal value is standard for bandgap-like compensation. Consider the DO-35 package size for board space constraints. Verify that the 0.5 mA test current aligns with the system's biasing capabilities and power budget requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These devices are designed to provide stable reference voltages with very low temperature coefficients. The series includes various voltage options and tolerance grades, with the '-1' suffix denoting the internal metallurgical bond option for improved mechanical strength.

Single Zener Diodes Replacement Considerations

Check for JANTX or JANTXV prefixed variants for higher military qualifications. Other manufacturers may offer equivalent 6.4 V temperature-compensated Zener diodes in DO-35 packages, but verify temperature coefficient and tolerance specifications carefully.
