Procurement Notes

Verify component authenticity by checking the manufacturer marking code against official datasheet specifications. Confirm compliance with environmental directives such as RoHS 2.0 and ensure the package type matches the required mechanical footprint. Review thermal derating curves for high ambient temperature operations to maintain safe junction temperatures.

Selection Notes

Select this component based on the specific 6.8 V nominal breakdown voltage requirement. Ensure the application operates within the specified maximum power dissipation limits and accounts for thermal resistance variations relative to lead length. Verify that the leakage current and impedance parameters meet the precision requirements of the target circuit design.

Part Context

This part belongs to the 1N4728A series manufactured by Panjit International Inc., which covers a voltage range from 3.3 V to 68 V.
