RF Diode Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Check for Product Change Notices (PCN) regarding manufacturing updates. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet. Validate package orientation markings against schematic requirements before assembly.

RF Diode Selection Notes

Select this variant when high reverse voltage blocking is required alongside quad diode functionality. The Ring Quad topology offers specific connectivity advantages over standard common cathode or bridge configurations. Consider the higher series resistance compared to lower voltage families when designing for efficiency. Verify that the SOT-363 footprint matches the PCB layout constraints.

RF Diode Part Context

This component belongs to the HSMS-280x family of surface mount Schottky diodes designed by Broadcom Limited. The series provides various configurations including single, dual, and quad options in packages like SOT-23, SOT-323, and SOT-363. The HSMS-280x line is distinguished by its high breakdown voltage characteristics, making it distinct from the lower voltage HSMS-281x and HSMS-282x families.

RF Diode Replacement Considerations

Direct substitutes within the same family include other HSMS-280x variants with different pinouts such as HSMS-280M (Common Cathode Quad) or HSMS-280P (Bridge Quad). Ensure the replacement part maintains the required 70 V breakdown voltage and fits the SOT-363 package form factor.
