1N4568/TR

Single Zener Diodes Overview

The Microchip Technology 1N4568/TR is a temperature compensated Zener reference diode with a nominal voltage of 6.4 V and a test current of 0.5 mA. It features a maximum reverse current of 2 µA at 3 V and a dynamic impedance of 200 Ohms. The device operates within a temperature range of -55°C to +100°C and dissipates up to 500 mW. The TR suffix indicates tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range for instrumentation applications
• Features internal metallurgical bonding for structural integrity
• Offers flexible axial-leaded mounting terminals in a hermetically sealed glass case

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Circuit designs demanding low voltage drift across temperature variations
• Temperature compensated reference systems

Single Zener Diodes Procurement Notes

Verify the specific electrical characteristics against the official datasheet, particularly the temperature coefficient and reverse current limits. Confirm that the tape and reel packaging meets the required handling specifications for automated assembly processes. Ensure the component aligns with the intended thermal management requirements for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a precise 6.4 V reference with tight temperature stability is required. The 0.5 mA test current option suits low-power designs. Consider the DO-7 package dimensions for board layout constraints. Verify compatibility with existing circuit biasing networks to maintain optimal voltage-temperature stability during operation.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A series of Zero-TC Reference Diodes manufactured by Microsemi (now Microchip). These devices are designed to provide stable voltage references with minimal variation over temperature. The series includes various operating currents and temperature coefficients to accommodate different precision requirements.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N4568 variants from different manufacturers or military qualified versions like JANTX1N4568A-1. Ensure replacement components match the 6.4 V nominal voltage, 0.5 mA test current, and DO-7 package style.
