Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and lead condition upon receipt. Ensure compliance with project specifications regarding RoHS status, as this specific part may not meet current environmental directives. Validate electrical parameters against test reports before integration into critical designs.

Single Zener Diodes Selection Notes

Select this component when a 120 V Zener voltage with 5% tolerance is required in a standard axial package. Consider the 1 W power rating and operating temperature range relative to circuit thermal conditions. Compare impedance values against other series members if tighter regulation is needed. Verify availability status as production lifecycle stages affect long-term sourcing.

Single Zener Diodes Part Context

This device belongs to the Microsemi Zener diode family, specifically utilizing the DO-204AL axial leaded package format. It shares design similarities with other parts in the series but is distinguished by its specific 120 V nominal voltage and 1 W power handling capability. The product line supports various voltage options within the same physical footprint.
