MADP-007433-12790T

RF Diode Overview

The MADP-007433-12790T is a single silicon PIN diode from the MACOM SMPP series, housed in an SC-79 (Case Style 1279) surface mount package. It features a reverse voltage rating of 75 V and a maximum total capacitance of 0.35 pF at 20 V. The device exhibits a maximum series resistance of 1.5 Ω at 10 mA forward bias current and has a nominal minority carrier lifetime of 0.2 µs with a 0.4 mil I-region thickness. Designed for microwave control circuits, it supports an operating temperature range of -65°C to +125°C and delivers a maximum RF CW incident power of 29 dBm.

• Low distortion performance suitable for attenuator applications
• High isolation characteristics for series and series-shunt switching through 3 GHz
• Lead-free surface mount construction compliant with RoHS standards

RF Diode Applications

• Current controlled attenuator circuits
• Series and series-shunt switches
• Microwave control circuit applications

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package style and configuration. Ensure that the SC-79 footprint matches the design requirements. Confirm compliance with environmental directives such as RoHS before finalizing procurement specifications.

RF Diode Selection Notes

Select this component when low capacitance and high isolation are required for switching applications up to 3 GHz. Compare the 1.5 Ω series resistance against other models like the MA4P7436 if lower on-state resistance is needed. Consider the 0.2 µs carrier lifetime for speed requirements in control loops.

RF Diode Part Context

This part belongs to the MADP-007433 series within the broader SMPP family of surface mount plastic PIN diodes. It shares electrical characteristics with the MA4P7433 series but utilizes the SC-79 package instead of SOT-23 or SOT-323 variants. The series is engineered for low distortion in attenuator circuits.

RF Diode Replacement Considerations

The MA4P7433-12790T is the direct equivalent within the same package style. Other series members like the MADP-007436 offer lower resistance but higher capacitance. Verify pinout compatibility when substituting with common cathode or series tee configurations.
