• RoHS compliant lead-free surface mount construction

RF Diode Applications

• Microwave control circuits
• RF switches
• Attenuators

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and packaging format. Ensure that the selected variant matches the required thermal and electrical specifications for the intended application environment. Cross-reference the manufacturer's datasheet for any updates regarding compliance standards or recommended mounting procedures before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a balanced performance profile is required for both switching and attenuation tasks. The 0.4 µs carrier lifetime and 0.25 pF capacitance make it appropriate for general RF control applications up to 3 GHz. Consider the 100 V reverse voltage rating for circuit protection requirements and ensure the SOT-23 footprint aligns with the PCB layout constraints.

RF Diode Part Context

This device belongs to the MACOM SMPP Series of Surface Mount Plastic PIN Diodes. It shares the SOT-23 package form factor with other series members like the MA4P7436 and MA4P7433 but offers distinct electrical parameters tailored for general-purpose utility rather than specialized low-resistance or ultra-low-capacitance roles.

RF Diode Replacement Considerations

The MA4P7447 and MADP-007155 are documented general-purpose alternatives within the same series. These parts share similar functional classifications but exhibit different electrical characteristics, such as higher capacitance and resistance values.
