RF Diode Procurement Notes

Verify availability through authorized distributors or secondary market suppliers, as the manufacturer has officially discontinued this part number. Confirm that the specific lot date codes meet project requirements due to potential age-related degradation. Ensure compliance with current export control regulations and verify that the hermetic seal integrity remains intact for the intended operating environment.

RF Diode Selection Notes

Consider the discontinuation status when planning long-term production runs. Evaluate alternative components from the same family or newer generations if supply chain stability is critical. Verify that the 130 C/W thermal resistance meets the system's heat dissipation requirements without active cooling. Check compatibility with existing PCB footprints and assembly processes for legacy components.
