MA4E2072M-1068T

RF Diode Overview

The MA4E2072M-1068T is a silicon Schottky crossover quad diode from the MACOM MA4E2072 series, housed in an SOT-143 (ODS-1068) surface mount package. It features closely matched junctions to minimize variation in capacitance, forward voltage, and dynamic resistance across the four internal diodes. The device operates within a temperature range of -65°C to +125°C and supports soldering temperatures up to 260°C. Key electrical specifications include a typical forward voltage of 363 mV, a maximum forward voltage of 400 mV, a maximum delta Vf of 5 mV, a typical junction capacitance of 0.5 pF, and a maximum dynamic resistance of 7.0 ohms.

RF Diode Feature Summary

• Crossover quad configuration with closely matched junctions for minimized parameter variation
• Lead-free and RoHS compliant construction with matte tin plating
• Designed for high-volume applications using automatic pick-and-place assembly

RF Diode Applications

• Mixer applications utilizing RF signals
• High-volume surface mount manufacturing processes

RF Diode Procurement Notes

Verify component authenticity by cross-referencing the part number MA4E2072M-1068T with official MACOM documentation. Confirm that the ordering suffix corresponds to the tape and reel delivery format specified in the datasheet. Ensure compliance with lead-free and RoHS requirements during procurement to match the matte tin plating characteristics described in the product specifications.

RF Diode Selection Notes

Select this component when a medium barrier height Schottky diode is required for mixer circuits. The M suffix indicates specific forward voltage and dynamic resistance parameters distinct from the L or H variants. Verify that the SOT-143 package dimensions and pinout align with the PCB footprint design. Consider the thermal management capabilities relative to the specified operating temperature range and junction temperature limits.

RF Diode Part Context

This component belongs to the MA4E2072 series of surface mount Schottky crossover quads manufactured by MACOM Technology Solutions. The series offers low, medium, and high barrier height options to suit different mixer performance requirements. All variants share the same SOT-143 package outline and general feature set, differing primarily in their electrical characteristics such as forward voltage and dynamic resistance.

RF Diode Replacement Considerations

The MA4E2072L-1068T and MA4E2072H-1068T are confirmed substitutes within the same series. Selection depends on whether lower or higher barrier heights are needed compared to the medium barrier height of the MA4E2072M variant. Electrical parameters must be verified against circuit requirements before substitution.
