CAS120M12BM2

Overview

The CAS120M12BM2 is a 1200 V, 120 A all-Silicon Carbide high-performance switching optimized half-bridge module from Wolfspeed. It features an industry standard 62 mm footprint with a copper baseplate and aluminum nitride insulator. The device operates within a virtual junction temperature range of -40 °C to 150 °C. Key electrical parameters include a maximum drain-source voltage (VDS) of 1200 V, a recommended gate-source operating voltage (VGS(op)) of -5/+20 V, and a typical on-state resistance (RDS(on)) of 13.0 mΩ at 120 A. Continuous DC drain current reaches 200 A at 25 °C case temperature. Power dissipation is rated at 1000 W.

Feature Summary

• Ultra-low loss and high-frequency operation enabled by zero reverse recovery from diodes and zero turn-off tail current from MOSFETs.
• Normally-off, fail-safe device operation ensuring inherent safety during gate signal loss.
• Robust construction utilizing a copper baseplate and aluminum nitride insulator for superior thermal management.

Applications

• Railway & Traction systems
• Solar & Renewable Energy inverters
• EV Charging infrastructure
• Industrial Automation & Testing equipment

Procurement Notes

Verify the specific revision level against the latest official datasheet before procurement, as product specifications are subject to change without notice. Confirm that the intended application does not involve life-support or critical safety systems where failure could cause injury, as this component is not designed for such use. Ensure compliance with RoHS2 directives and check for any recent Product Change Notifications regarding packaging or manufacturing origin updates.

Selection Notes

Select this module when transitioning from 62 mm IGBT packages to achieve faster time-to-market with minimal development effort. Consider its low switching and conduction losses for applications requiring increased system efficiency. Verify that the required continuous current and power dissipation capabilities align with the thermal constraints of the target heatsink design, particularly noting the derating curves provided in the datasheet.

Part Context

This component belongs to the BM2 series of 62 mm footprint modules offered by Wolfspeed. It represents a mid-range solution within their portfolio, bridging the gap between lower-power discrete solutions and higher-current heavy-duty modules. The BM2 platform is designed for industrial and harsh environment applications, providing a standardized form factor compatible with existing IGBT-based designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the verified source material. Designers migrating from other manufacturers' 62 mm modules should verify pinout compatibility and thermal resistance values carefully, as direct drop-in replacements may require schematic adjustments due to differing stray inductance and gate drive requirements.
