RF Diode Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to remaining stock or third-party distributors. Verify end-of-life status and lead times carefully before procurement planning. Ensure compatibility with existing designs due to potential supply chain discontinuation.

RF Diode Selection Notes

Select this part for applications requiring a compact RF switch with low capacitance. The SOT-323 package suits space-constrained layouts. Consider the 50V reverse voltage rating for circuit protection needs. Evaluate thermal management requirements given the 150°C junction limit. Check for available replacement components due to obsolescence.
