RF Diode Procurement Notes

Verify component authenticity through authorized Skyworks channels or certified distributors. Confirm RoHS compliance status via the manufacturer's Certificate of Conformance prior to integration. Ensure proper electrostatic discharge handling procedures are followed during storage and assembly, as the bare die is sensitive to static charges. Review the latest datasheet revisions for any updates to mechanical dimensions or electrical limits.

RF Diode Selection Notes

Select the CLA4610-000 for designs requiring high-power handling capabilities in multi-stage limiter configurations. Its planar structure distinguishes it from low-capacitance mesa devices intended for cleanup stages. Evaluate the 80–120 V breakdown voltage range against system surge requirements. Consider the 0.13 pF junction capacitance for insertion loss characteristics at target operating frequencies.

RF Diode Part Context

The CLA4610-000 belongs to the Skyworks CLA Series of silicon limiter diode bondable chips. This family comprises eleven distinct chip designs varying in intrinsic region base widths and capacitances. While some variants utilize mesa constructions for low-level applications, the CLA4610-000 specifically employs a planar design suited for robust power handling in commercial and defense radar environments.

RF Diode Replacement Considerations

Direct replacements within the same series include CLA4606-000, CLA4607-000, and CLA4608-000, which share similar planar high-power architectures. Substitution requires verification of matching breakdown voltage ranges and thermal resistance values to ensure circuit compatibility.
