RF Diode Procurement Notes

Verify component status before procurement planning. Official documentation indicates the DME3927-000 variant is discontinued. Confirm availability of active alternatives within the same product family if long-term supply assurance is required for production systems.

RF Diode Selection Notes

Select this component when medium barrier height is required for specific mixer impedance matching. Ensure the application utilizes compatible die attach methods such as non-conductive epoxy or eutectic processes. Verify that the operating environment remains within the specified absolute maximum ratings to maintain device reliability.

RF Diode Part Context

This part belongs to the Skyworks Silicon Beamless Schottky Diodes family, which includes pairs and quads with varying barrier heights. The DME3927-000 specifically represents the medium barrier option within the ring quad configuration, intended for use in double-balanced mixer architectures requiring matched electrical characteristics.

RF Diode Replacement Considerations

The datasheet explicitly lists DME3927 as discontinued. Consider substituting with other medium barrier variants from the same family, such as DME3930-000, DME3933-000, or DME3943-000, depending on the required package outline and circuit topology.
