RF Diode Procurement Notes

Verify the specific suffix T106 against the official datasheet to confirm tape-and-reel packaging quantities and marking codes. Ensure the component meets RoHS3 compliance requirements for the target assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

RF Diode Selection Notes

Select this component when a common-cathode switching diode with low capacitance is required for RF applications. The SOT-323 package suits space-constrained designs. Verify that the 35V reverse voltage and 150mW power dissipation ratings align with the circuit's operational limits and thermal management strategy.

RF Diode Part Context

This part belongs to the DAN235 series of switching diodes from ROHM Semiconductor. The series includes variants such as DAN235FM, DAN235ETL, and DAN235U, which share similar form factors but may differ in specific electrical characteristics or automotive qualification status. The DAN235FMT106 represents a standard commercial grade version.

RF Diode Replacement Considerations

Direct replacements must match the SOT-323 footprint and common-cathode configuration. Verify that substitute components meet the 35V reverse voltage and 1.2pF capacitance specifications to maintain RF performance integrity in existing designs.
