RF Diode Procurement Notes

Verify the specific suffix T106 against the official datasheet to confirm packaging details and tape-and-reel quantities. Ensure the component meets RoHS compliance requirements for the target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and supply chain integrity before procurement.

RF Diode Selection Notes

Select this component when a common cathode band switch diode with low capacitance is required for RF applications. Verify that the 35V reverse voltage rating aligns with the circuit's peak inverse voltage. Confirm that the UMD3 package dimensions fit the PCB footprint constraints. Check if the 125°C junction temperature limit satisfies the thermal management requirements of the final assembly.

RF Diode Part Context

The DAN235U series belongs to ROHM's lineup of band switch diodes intended for RF applications. The T106 suffix typically denotes the taping packaging format with a standard reel quantity. This series is distinct from general-purpose switching diodes due to its optimized parasitic parameters for high-frequency operation.

RF Diode Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternatives based on matching pinout, package type (UMD3/SOT-323), reverse voltage, and capacitance specifications.
