RF Diode Procurement Notes

Verify the specific ordering suffix TR1G corresponds to the required tape and reel quantity of 3000 units per 7-inch reel. Confirm that the SOT-23 package marking code A0 matches the design requirements. Ensure compliance with RoHS standards and lead-free assembly processes during procurement.

RF Diode Selection Notes

Select this component when high breakdown voltage is critical for the circuit design. The HSMS-280x series exhibits higher series resistance compared to other families; therefore, it is best suited for applications where voltage handling outweighs the need for minimal resistive loss. Verify thermal management capabilities given the 500°C/W thermal resistance rating.
