• Military and aerospace electronic systems
• High-reliability instrumentation and measurement equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix A-1 against the official Microchip datasheet to confirm the exact tolerance and temperature coefficient specifications. Ensure the procurement channel provides valid military lot traceability and certification documents required for JAN grade components. Confirm RoHS status as these legacy military parts may have specific compliance classifications distinct from commercial equivalents.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand exceptional voltage stability under varying thermal conditions. The narrow 0.05% tolerance makes it superior to standard Zener diodes for precision references. Consider the DO-35 package constraints for PCB layout and ensure the power dissipation limits are respected within the system's thermal management strategy.

Single Zener Diodes Part Context

This part belongs to the JAN series of discrete semiconductors produced by Microchip Technology, formerly Microsemi. The JAN designation indicates compliance with strict military reliability standards. It is part of a broader family of temperature-compensated Zener diodes designed for high-stakes applications where standard commercial components would fail due to environmental stress or parameter drift.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JAN-series temperature-compensated Zener diodes with matching 6.4 V ratings and 0.05% tolerance, such as the JAN1N4568A-1 if voltage compatibility allows. Verify pinout and package dimensions (DO-35) before substitution. Cross-reference with MIL-PRF-19500 specifications to ensure equivalent performance characteristics.
