RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact package style and tape-and-reel specifications. Ensure that the component meets all applicable environmental compliance standards required for the intended assembly process before finalizing procurement orders.

RF Diode Selection Notes

Select this component when circuit requirements prioritize minimum parasitic capacitance over low series resistance. The 0.35 pF capacitance makes it suitable for high-frequency switching applications where signal leakage must be minimized, distinguishing it from lower-resistance alternatives in the same product family.

RF Diode Part Context

This part belongs to the MACOM SMPP series of surface mount plastic PIN diodes. It shares the electrical characteristics of the MA4P7433 family but utilizes the SOD-323 package instead of the SOT-23 or SC-70 variants found in other suffixes within the same series.

RF Diode Replacement Considerations

Direct replacements include other MA4P7433 variants such as MA4P7433-287T or MA4P7433-1146T, provided the PCB footprint accommodates the specific case style differences between SOD-323 and SOT-23/SOT-323 packages.

RF Diode FAQ

What is the nominal minority carrier lifetime for the MA4P7433-1141T?

The nominal minority carrier lifetime is 0.2 µs, measured at a forward current of 10 mA and reverse current of 6 mA with 90% recovery.

How does the MA4P7433 series differ from the MA4P7436 series?

The MA4P7433 series offers lower capacitance (0.35 pF) for higher isolation, whereas the MA4P7436 series provides lower series resistance (0.5 Ω) for better insertion loss performance.

Is the MA4P7433-1141T available in dual configurations?

No, the -1141T suffix denotes a single diode configuration. Dual configurations such as common cathode or common anode pairs are available in different part numbers like MA4P7433CK-1141T or MA4P7433CA-1141T.
