RF Diode Procurement Notes

Verify the specific ordering suffix BLKG to confirm bulk packaging requirements. Confirm RoHS compliance status through official documentation before integration. Check for any product change notices or obsolescence notifications that may affect long-term supply stability. Ensure the supplier provides valid traceability data for quality assurance purposes.

RF Diode Selection Notes

Select this component when high reverse breakdown voltage is required compared to standard Schottky alternatives. Consider the higher series resistance inherent to the HSMS-280x family versus lower resistance options like the HSMS-282x if current handling is critical. Verify that the SOT-23 package dimensions fit the target PCB footprint constraints.

RF Diode Part Context

This part belongs to the HSMS-280x family of surface mount RF Schottky barrier diodes. The family includes various configurations such as pairs, quads, and bridges, all utilizing the same underlying diode chip technology. The HSMS-280x series is distinctively characterized by its high voltage capabilities, differentiating it from the low-noise HSMS-281x and low-resistance HSMS-282x families.

RF Diode Replacement Considerations

Direct substitutes within the same family include HSMS-2800-BLKG (Single), HSMS-2802-BLKG (Series), and HSMS-2804-BLKG (Common Cathode). For applications requiring lower series resistance, consider the HSMS-282x series. For low flicker noise requirements, evaluate the HSMS-281x series.
