Single Zener Diodes Procurement Notes

Verify the specific suffix 'G' indicates the glass body variant when sourcing replacements. Confirm RoHS compliance status as historical Microsemi data may vary by production batch. Ensure the supplier provides traceability documentation for hermetic sealing integrity. Cross-reference the manufacturer's current datasheet for any updates to mechanical dimensions or maximum ratings before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed package is required for high-reliability applications. The glass DO-41 package offers superior thermal performance compared to plastic equivalents. Consider the 100V breakdown voltage and 1W power rating against circuit requirements. Evaluate the operating temperature range to ensure compatibility with the intended environment.

Single Zener Diodes Part Context

This part is part of the widely used 1N47xx series of 1-watt Zener diodes. The 'G' suffix specifically denotes the glass-body option, which provides hermetic sealing and higher temperature ratings compared to the plastic-bodied variants. It serves as a direct equivalent to other manufacturers' 1N4764 devices within the same JEDEC specification framework.

Single Zener Diodes Replacement Considerations

Equivalent parts include the MSP1N4764PE3 (plastic body) and SMBG4764C-TR13 (surface mount). Verify that replacement packages match the physical footprint and lead configuration of the original design.
