RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The TR2G suffix indicates tape and reel packaging containing 10,000 devices per 13-inch reel. Ensure compliance with RoHS standards and lead-free requirements during procurement. Confirm availability status directly with authorized distributors or the manufacturer before initiating orders.

RF Diode Selection Notes

Select this component when designing circuits requiring minimal parasitic inductance for high-frequency performance up to 3 GHz. The dual cathode configuration allows for series connection of both leads to further reduce inductance in microstrip layouts. Verify that the 100 V breakdown voltage meets the peak inverse voltage requirements of the target application environment.

RF Diode Part Context

This part belongs to the HSMP-481x series of surface mount RF PIN diodes. The series includes variants such as HSMP-4810 and HSMP-481B, distinguished by their internal lead configurations. The HSMP-481B specifically utilizes a dual cathode arrangement, enabling flexible circuit topologies for attenuators and switches in compact surface mount designs.

RF Diode Replacement Considerations

Direct substitutes include other parts from the HSMP-481x family, such as HSMP-4810-BLK or HSMP-481B-BLK, provided the package and electrical characteristics align with the design requirements.
