RF Diode Procurement Notes

Verify the specific case style availability against the Package Availability Table on page 7 of the datasheet. Confirm that the selected package meets the required parasitic capacitance constraints for your circuit design. Ensure compliance with RoHS directives if applicable. Check for any specific MIL-STD screening requirements if intended for military use.

RF Diode Selection Notes

Select this component when a 500 V minimum reverse voltage rating is required alongside low capacitance characteristics. Consider the Case Style 36 package dimensions and thermal resistance limits. Evaluate the 2 µs carrier lifetime against system speed requirements. Verify that the 0.45 Ω series resistance fits within the insertion loss budget of the application.

RF Diode Part Context

This part belongs to the MA4P505 base series, which includes variants available in Case Styles 36, 255, and 1072T.
