CBB032M12FM3

Overview

The CBB032M12FM3 is a 1200 V, 32 mΩ Silicon Carbide full-bridge power module from Wolfspeed. It features four N-channel MOSFETs with a DC continuous drain current of 39 A at THS = 50 °C and TVJ ≤ 150 °C. The maximum gate-source voltage is -4 to +15 V, with transient excursions allowed up to -10 V and +23 V. Operating junction temperature ranges from -40 °C to 150 °C continuously, extending to 175 °C intermittently. The module includes an integrated NTC thermistor rated at 5.0 kΩ at 25 °C and utilizes press-fit pins for assembly.

Feature Summary

• Fully SiC MOSFET-based architecture providing ultra-low switching and conduction losses
• Press-fit pin connection system designed for simplified prototyping and manufacturing assembly
• Integrated NTC thermistor for precise thermal monitoring within the module
• Compliance with UL STD 1557 standards for electrically isolated semiconductor devices

Applications

• Isolated DC-DC converters
• High-efficiency inverters and converters
• Electric vehicle (EV) charging infrastructure
• Renewable energy systems and smart-grid distributed generation

Procurement Notes

Verify the specific ordering suffix when purchasing. The 'T' suffix indicates the inclusion of pre-applied phase change thermal interface material, whereas the standard version does not include it. Confirm that the selected variant matches the thermal management strategy required by the target application design.

Selection Notes

Select this component based on the 1200 V breakdown voltage and 32 mΩ on-state resistance requirements. Ensure the heatsink temperature remains within limits to maintain the specified 39 A continuous current rating. Consider the stray inductance of 14.2 nH when designing the PCB layout to optimize switching performance and minimize voltage overshoot during operation.

Part Context

This module belongs to the WolfPACK FM series, which provides a compact, industry-standard footprint for medium-power applications. It serves as a bridge between discrete components and high-current modules, offering scalability for designs requiring efficient power density without the complexity of custom packaging solutions.

Replacement Considerations

Direct replacements are limited due to the specific full-bridge configuration and press-fit form factor. Evaluate other WolfPACK FM series modules like the CBB021M12FM3 for lower resistance options, or verify compatibility with existing gate driver boards such as the CGD1700HB2M-UNA before substituting.
