RF Diode Procurement Notes

Verify the component status before procurement as availability may vary. Confirm that the ordering suffix TR2G corresponds to the specific tape and reel quantity and lead-free specification required for your assembly process. Ensure compatibility with standard surface mount reflow profiles.

RF Diode Selection Notes

Select this part when low flicker noise is critical compared to other Schottky families. The HSMS-281x series offers a balance between breakdown voltage and series resistance. Verify that the SOT-23 package dimensions fit the PCB footprint constraints and that the 20V breakdown rating meets the circuit's peak inverse voltage requirements.

RF Diode Part Context

This component belongs to the HSMS-281x family of surface mount RF Schottky diodes. The series includes single, dual, and quad configurations such as common anode, common cathode, and bridge quads. The HSMS-2812 specifically denotes the series-connected dual version within this lineup.

RF Diode Replacement Considerations

Other parts in the HSMS-281x series share similar characteristics but differ in internal configuration. For example, HSMS-2810 is a single diode, while HSMS-2814 is a common cathode pair. Ensure the replacement matches the required series connection topology.
