MMP4402-GM2/TR

RF Diode Overview

The MMP4402-GM2/TR is a single PIN diode manufactured by Microchip Technology, designed for RF applications. It features a peak reverse voltage of 75V and operates within a temperature range of -55°C to 150°C. Key electrical parameters include a capacitance of 2pF at 0V and 1MHz, and a resistance of 1.5 ohms at 100mA forward current and 100MHz frequency. The component is housed in a 2-SMD, no-lead package and is supplied in tape and reel packaging.

RF Diode Feature Summary

• Single PIN diode configuration optimized for RF signal processing
• High thermal stability with an operating temperature range extending to 150°C
• Low capacitance characteristics suitable for high-frequency switching applications

RF Diode Applications

• RF switching circuits
• Attenuator designs
• Phase shifters

RF Diode Procurement Notes

Verify the specific ordering suffix GM2/TR against the manufacturer's official datasheet to ensure correct package type and reel quantity. Confirm RoHS3 compliance status as per the latest product change notices. Cross-reference the DigiKey part number 150-MML4402-GM2/TR-ND if sourcing through that distributor, noting potential alias variations for the same base component MML4402.

RF Diode Selection Notes

Select this component when a single PIN diode with 75V reverse voltage rating is required for SMD assembly. Ensure the application frequency aligns with the specified 1.5 ohm resistance at 100MHz. Verify that the 2-SMD no-lead footprint matches the PCB layout constraints. Consider the -55°C to 150°C operating range for environmental suitability.

RF Diode Part Context

This device belongs to the MML4400 series of RF PIN diodes from Microchip Technology. It shares the base model number MML4402 but differs in packaging and handling specifications due to the GM2/TR suffix indicating surface mount tape and reel delivery. It is distinct from hermetically sealed variants or different package styles within the broader PIN diode portfolio.

RF Diode Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source data. Engineers should evaluate other Microchip MML4400 series variants with compatible 2-SMD footprints and similar electrical parameters (75V Vr, 2pF Cj) for potential cross-compatibility. Verify pinout and thermal characteristics before substitution.
