1N5525/TR

Overview

The Microchip Technology 1N5525/TR is a Zener diode with a nominal voltage of 6.8V and a power dissipation of 0.5W. It features a maximum Zener impedance of 30 ohms and operates within a temperature range of -65°C to +175°C. The component utilizes an axial-lead DO-35 glass package and is supplied in tape-and-reel format.

Feature Summary

• Provides stable voltage regulation at 6.8V with low impedance characteristics
• Constructed with hermetically sealed glass encapsulation for environmental protection
• Designed for high-temperature operation up to 175°C junction temperature

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing reel handling equipment if automated assembly is planned. Cross-reference part numbers carefully as minor suffix variations may indicate different tolerance grades or testing standards.

Selection Notes

Select this component when a 6.8V regulation point is required in space-constrained axial packages. Consider the 30-ohm impedance value for load regulation requirements. Verify that the 0.5W power rating suffices for the expected current levels in the target application environment.

Part Context

This device belongs to the 1N55xx series of low-voltage avalanche Zener diodes manufactured by Microchip Technology. The series offers various voltage options in the DO-35 package, catering to general-purpose regulation needs. The /TR suffix indicates tape-and-reel packaging suitable for high-volume automated placement processes.

Replacement Considerations

Consult official substitution guides for equivalent parts from other manufacturers. Verify pinout compatibility and thermal performance before replacing. Ensure any substitute meets the same MIL-PRF-19500/437 qualification if military-grade reliability is required.
