Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'PBFREE' corresponds to lead-free plating as defined by manufacturer standards. Confirm the 'BK' designation indicates bulk packaging if required for specific handling procedures. Ensure the part number matches the exact series specifications for the 39 V Zener voltage variant. Cross-reference the marking code C4716 on the physical component to validate authenticity against the datasheet table.

Single Zener Diodes Selection Notes

Select this component when circuit design demands minimal quiescent current consumption alongside precise voltage clamping. The DO-35 package is suitable for through-hole mounting in standard industrial or commercial enclosures. Consider the 500 mW power rating relative to ambient thermal conditions to ensure junction temperatures remain within the specified -65°C to +200°C operational limits during continuous use.

Single Zener Diodes Part Context

This device belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8 V to 43 V, all sharing common electrical characteristics such as 50 μA test current and 5% tolerance. The 1N4716 specifically targets the 39 V segment of this lineup, offering consistent performance metrics aligned with the broader family specifications.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent substitutes include parts from other manufacturers designated as 1N4716. Verify that alternative sources maintain the same 500 mW power dissipation, DO-35 package outline, and 5% voltage tolerance to ensure functional compatibility without redesigning the host circuitry.
