150CMQ045

Overview

The 150CMQ045 is a Schottky barrier rectifier module manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 45V and an average forward rectified current rating of 75A per leg in a common cathode configuration. The device utilizes a TO-249 package, designed for high-efficiency power conversion applications requiring low forward voltage drop and fast switching characteristics.

Feature Summary

• Schottky barrier technology for low noise switching
• Common cathode dual diode configuration
• Lead-free and RoHS compliant construction

Applications

• DC-DC converters
• Power supply freewheeling circuits
• Solar panel rectification

Procurement Notes

Verify the specific datasheet version with SMC Diode Solutions prior to ordering, as product specifications may be updated. Confirm that the required thermal management solutions are compatible with the TO-249 package dimensions and mounting requirements for the intended application environment.

Selection Notes

Select this component when a 45V reverse voltage rating and 75A continuous current capability are required in a compact module form factor. Ensure the operating junction temperature range aligns with the system's thermal design constraints and that the low forward voltage drop meets efficiency targets.

Part Context

This part belongs to the CMQ series of Schottky power modules from SMC Diode Solutions. These components are engineered for high-current applications where standard discrete diodes would require complex parallel arrangements. The series offers standardized pinouts and thermal characteristics for easier integration into existing power board designs.

Replacement Considerations

Direct substitutes include the 300CMQ045 and 201CMQ045 from the same manufacturer family, which share similar packaging and electrical topologies but differ in current ratings. Verify pin compatibility and thermal resistance values before substitution.
