Single Zener Diodes Procurement Notes

Verify the manufacturer designation on the component marking against official SMC Diode Solutions documentation to confirm authenticity. Ensure the specific orderable part number matches the required package style and tolerance specifications. Cross-reference datasheet revisions to confirm compliance with current environmental standards such as RoHS and REACH before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 17 V regulation point is required in a through-hole design. The DO-35 package accommodates standard PCB drilling patterns. Evaluate thermal management requirements to ensure the 0.5 W power rating remains sufficient under worst-case operating conditions. Confirm that the 19 Ohm impedance meets the dynamic regulation needs of the target circuit.

Single Zener Diodes Part Context

This component belongs to the industry-standard 1N52xx series of Zener diodes. These devices are widely utilized for basic voltage regulation tasks. The 1N5247B specifically targets applications needing a 17 V breakdown voltage. Its axial configuration allows for easy integration into legacy and modern through-hole printed circuit board layouts.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering the 1N5247B designation to verify pinout compatibility and parameter equivalence. Ensure substitute parts maintain the same DO-35 package dimensions and 17 V nominal voltage rating.
