Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the specific reel packaging configuration required by your assembly line. Confirm that the 'PBFREE' designation aligns with RoHS compliance requirements for your manufacturing process. Ensure the DO-35 package dimensions match your PCB footprint specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand minimal quiescent current consumption alongside stable voltage regulation. The 500 mW power rating allows for moderate current handling in compact axial packages. Consider the 5% tolerance band if tighter precision is not critical, as it provides cost-effective performance for general-purpose low-level stabilization tasks.

Single Zener Diodes Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes from Central Semiconductor. The series covers a voltage range from 1.8 V to 43 V, all sharing common electrical characteristics such as 50 μA test currents and 500 mW power dissipation capabilities. These devices are standardized for use in applications prioritizing low leakage and stable performance under varying thermal conditions.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes with 7.5 V nominal voltage and 500 mW ratings. Verify that substitute components meet the same 5% tolerance and low leakage specifications to ensure circuit compatibility without redesign.
