MA4P7447-1141T

RF Diode Overview

The MA4P7447-1141T is a single silicon PIN diode from the MACOM SMPP series, housed in an SOD-323 (Case Style 1141) surface-mount package. It serves as a general-purpose component for microwave control circuits, functioning effectively as both a switch and an attenuator. Key electrical specifications include a reverse voltage rating of 100 V, a maximum total capacitance of 1.20 pF at 20 V, and a maximum series resistance of 0.6 Ohms measured at 10 mA. The device features a nominal minority carrier lifetime of 1.0 µs and an I-region thickness of 0.8 mils.

RF Diode Feature Summary

• General-purpose design suitable for use as either a switch or an attenuator
• Low loss and high isolation characteristics for switching applications
• RoHS compliant lead-free surface mount plastic packaging

RF Diode Applications

• Microwave control circuits
• RF switches

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel configuration. Ensure that the required reverse voltage and capacitance ratings align with the circuit design requirements before finalizing procurement. Confirm compliance with current RoHS directives if applicable to the project specifications.

RF Diode Selection Notes

Select this component when a balance between low series resistance and moderate capacitance is required for general-purpose RF applications. Consider the 100 V reverse voltage rating and 0.6 Ohm series resistance for appropriate biasing conditions. Evaluate thermal derating coefficients if operating near maximum power dissipation limits.
