RF Diode Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and packaging format. Confirm that the component meets all applicable environmental compliance requirements for the intended deployment region before finalizing procurement orders.

RF Diode Selection Notes

Select this component when high isolation and low capacitance are prioritized over low series resistance. The common anode configuration simplifies biasing networks compared to single diodes or common cathode pairs. Ensure the required forward current does not exceed the absolute maximum ratings defined in the datasheet.

RF Diode Part Context

This part belongs to the MACOM SMPP series of surface mount plastic PIN diodes. It shares the same electrical characteristics as the single-diode MA4P7433-287T but integrates two devices in one package. Other variants in the series offer different I-region thicknesses to trade off between series resistance and capacitance.

RF Diode Replacement Considerations

The single-diode MA4P7433-287T serves as a functional equivalent if only one diode is required. For common cathode implementations, the MA4P7433CK-287T is the direct alternative. Verify pinout compatibility during board layout modifications.
