1N4689 TR TIN/LEAD

Overview

The Central Semiconductor Corp 1N4689 TR TIN/LEAD is a silicon unidirectional Zener diode housed in a hermetically sealed glass MELF-2 (DO-213AA) package. It provides a nominal Zener voltage of 5.1 V with a tight tolerance of 2%. The device supports a maximum power dissipation of 0.5 W and operates within a junction temperature range of -65 °C to +175 °C.

Feature Summary

Hermetically sealed glass encapsulation for environmental protection
High-reliability metallurgically bonded construction
Tight voltage tolerance for precision regulation

Applications

Precision voltage reference circuits
Overvoltage protection in sensitive electronics
Clamping applications in high-reliability systems

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and testing criteria. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability for critical applications.

Selection Notes

Select this component when a hermetically sealed, high-reliability Zener diode is required for harsh environments. The MELF-2 package offers robustness superior to standard plastic packages, while the 2% tolerance ensures precise voltage regulation compared to standard commercial grades.

Part Context

This part belongs to the 1N4689 series of small-signal Zener diodes manufactured by Central Semiconductor Corp. The series utilizes silicon planar technology and is designed for general-purpose regulation and clamping tasks where reliability and stability are prioritized over cost.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with equivalent MIL-spec or industrial-grade Zener diodes in the DO-213AA package before substitution.
