RF Diode Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm RoHS compliance requirements against specific project standards. Ensure the DO-41 through-hole package aligns with existing PCB footprint constraints. Validate that the 180V reverse voltage and 1W power dissipation meet circuit design margins. Check datasheet revisions for any parameter updates.

RF Diode Selection Notes

Select this component for applications requiring reliable RF switching with moderate power handling. The DO-41 package suits automated or manual through-hole assembly processes. Consider the 100 mA forward current limit when designing bias networks. Evaluate the 180V breakdown voltage against peak RF voltages to prevent device failure. Ensure thermal management strategies accommodate the 175°C maximum junction temperature.
