RF Diode Procurement Notes

Verify the specific package variant (SOT-323 or SOT-363) required for the design, as the datasheet covers multiple configurations under the HSMS-280x family. Confirm that the common cathode quad topology aligns with the circuit schematic before ordering. Ensure compliance with RoHS standards if applicable to the target market regulations.

RF Diode Selection Notes

Select this component when high reverse voltage blocking is necessary, distinguishing it from the lower voltage HSMS-281x and HSMS-282x families. Note that the higher series resistance compared to other families may impact efficiency in low-voltage, high-current scenarios. Evaluate the thermal resistance requirements based on the chosen package type for proper heat dissipation.
