1N4568E3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4568E3/TR is a temperature compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.001 %/°C. It operates at a test current of 0.5 mA, features a maximum reverse leakage 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, supports an operating temperature range from -65°C to +175°C, and dissipates up to 500 mW.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad operating ranges
• Internal metallurgical bond construction for reliability
• Hermetically sealed glass case providing ESD protection per MIL-STD-750 Method 1020

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm package type and military qualification status. Ensure the ordering code matches the required JEDEC registration and tolerance specifications. Confirm RoHS compliance details as indicated by the E3 suffix. Cross-reference the manufacturer's latest documentation for any packaging or assembly changes.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with tight temperature stability is required. The 0.5 mA test current option suits low-power applications. Verify that the DO-7 package dimensions fit the board layout. Consider tighter tolerance suffixes if standard 5% voltage accuracy is insufficient for the target circuit requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A series of Zero-TC Reference Diodes. The series offers various temperature coefficients and operating currents ranging from 0.5 mA to 4.0 mA. These diodes are designed for high-reliability environments and are available in multiple package styles including DO-7 and surface mount equivalents.

Single Zener Diodes Replacement Considerations

Equivalent parts within the 1N4565-1N4584A series may be considered if they match the 6.4 V nominal voltage and 0.001 %/°C temperature coefficient. Verify package compatibility and electrical characteristics such as dynamic impedance and leakage current before substitution.
