Procurement Notes
Verify current availability status as this component may be subject to discontinuation notices. Confirm RoHS compliance details through official datasheets prior to final procurement. Ensure ordering suffixes match required packaging specifications. Cross-reference with manufacturer PCNs for any recent design or material changes affecting integration.
Selection Notes
Select this component when a hyperabrupt capacitance-voltage characteristic is required for broad frequency agility. The SC-79 footprint suits space-constrained designs. Evaluate thermal management requirements against the specified operating temperature limits. Compare against standard abrupt junction alternatives if narrower tuning ranges suffice.
Part Context
This device belongs to Skyworks' portfolio of general-purpose and specialized varactor diodes. It complements other SC-79 packaged components like the SMV1763, offering distinct hyperabrupt characteristics. The series targets mobile and wireless infrastructure markets requiring reliable tuning elements.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Skyworks technical support for direct replacements or pin-compatible alternatives within the same product family.
