RF Diode Procurement Notes

Verify current availability status as the component may be subject to discontinuation or limited supply constraints. Confirm RoHS compliance details through official manufacturer documentation prior to integration. Ensure ordering suffixes match specific packaging requirements such as cut tape or reel formats. Cross-reference part numbers with authorized distributors to avoid counterfeit sources.

RF Diode Selection Notes

Select this component when a single PIN diode with moderate carrier lifetime is required for frequencies up to 2 GHz. The SOD-323 package suits space-constrained designs. Compare series resistance and capacitance values against circuit impedance requirements. Verify thermal management capabilities given the 250 mW power dissipation limit and operating temperature range.

RF Diode Part Context

This part belongs to the Skyworks SMP1304 series of PIN diodes. It shares the SOD-323 package form factor with other variants in the lineup but differs in internal doping profiles affecting carrier lifetime and capacitance. It serves as a discrete solution for analog RF signal control compared to integrated switch ICs.

RF Diode Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative Skyworks PIN diodes with similar Vr and Cj specifications if direct replacement is necessary.
