Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required plating configuration. The PBFREE designation indicates lead-free plating compliance. Confirm the specific tape and reel packaging quantity aligns with production needs. Ensure the manufacturer part number corresponds exactly to the 1N4717 specification before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 43 V reference is required with minimal quiescent current draw. The low leakage characteristic makes it suitable for high-impedance circuits. Consider the DO-35 package constraints for board layout. Evaluate thermal dissipation capabilities relative to ambient operating conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4678 through 1N4717 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8 V to 43 V. All devices in this family share similar electrical profiles, including 500 mW power dissipation and 5% tolerance, differing primarily in their specific Zener voltage ratings.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4717 equivalents in DO-35 packages. Verify that substitute components meet the same 500 mW power rating and 43 V nominal voltage specifications. Ensure compatibility with the low leakage current requirements of the original design.
