RF Diode Procurement Notes

Verify the specific suffix against official MACOM documentation to confirm package type and material specifications. Ensure compatibility with high-voltage circuit requirements given the 100 V breakdown rating. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference thermal resistance values for proper heat sinking design.

RF Diode Selection Notes

Select this component for applications requiring high voltage tolerance and significant power dissipation at lower RF frequencies. The 100 V breakdown and 12 W CW power rating distinguish it from standard low-power PIN diodes. Consider the axial lead ODS-402 package for through-hole mounting or chip form factors if surface mount integration is needed.

RF Diode Part Context

This part belongs to MACOM’s Kilovolt PIN diode family, which utilizes specialized epitaxial processes on floating zone silicon. This technology preserves carrier lifetime and interface quality better than traditional double-diffused methods. The series is designed for high-voltage, high-power RF switching where reliability and low leakage are critical.

RF Diode Replacement Considerations

Direct substitutes within the same series include MA4P504 variants and MA4P7436CA models. Verify pinout and thermal characteristics when considering cross-brand alternatives. Ensure any replacement maintains the 100 V minimum breakdown voltage and similar capacitance levels.
