RF Diode Procurement Notes

Verify current availability status as the component lifecycle is listed as discontinued or obsolete. Confirm RoHS compliance details through official documentation before procurement. Check for valid substitute part numbers if new production units are required. Ensure packaging specifications match design requirements.

RF Diode Selection Notes

Select this component for applications requiring robust RF limiting in the Ka band. Consider the low capacitance value for high-frequency signal integrity. Evaluate the thermal resistance rating against system heat dissipation capabilities. Verify that the 15 V breakdown voltage aligns with the circuit's peak reverse voltage limits.

RF Diode Part Context

This part belongs to the Skyworks CLA series of silicon limiter diodes. The series includes various models with different breakdown voltages and package types. The CLA4602-240 specifically uses a hermetic seal, distinguishing it from surface-mount variants in the same family. It is intended for high-reliability environments where long-term stability is critical.

RF Diode Replacement Considerations
