RF Diode Procurement Notes

Verify the specific ordering suffix matches the required package style. Confirm RoHS compliance status if restricted substances are a constraint. Check for military screening requirements such as MIL-STD-750 if applicable to the end application. Ensure thermal management aligns with the specified power dissipation limits.

RF Diode Selection Notes

Select this component when a 500 V breakdown voltage is necessary alongside fast switching speeds. The ODS-258 package offers a balance of low parasitic capacitance and robust mechanical mounting. Compare against the MA4P506-30 or MA4P506-1072T if alternative form factors are needed while maintaining identical electrical characteristics.

RF Diode Part Context

This part belongs to the MA4P506 base product line, which provides 500 V rated PIN diodes. The standard package is typically style 30, but the chip can be mounted in various styles including the 258. This flexibility allows designers to choose between leaded and surface mount options without changing the core semiconductor specifications.

RF Diode Replacement Considerations

Direct substitutes include other MA4P506 variants with different packages, such as MA4P506-30 or MA4P506-1072T. Verify that the alternative package's parasitic capacitance meets the circuit requirements.
