CAS300M17BM2

Overview

The CAS300M17BM2 is a silicon carbide half-bridge power module from Wolfspeed, designed for high-efficiency and high-frequency applications. It features an industry-standard 62 mm footprint with a copper baseplate and aluminum nitride insulator. The module integrates C2M MOSFETs and Z-Rect diodes, offering a drain-source voltage of 1700 V and a typical on-state resistance of 8.0 mΩ at 25 °C. Continuous drain current reaches 325 A at 25 °C case temperature, while the source-drain diode current is rated at 556 A. Stray inductance is limited to 15 nH between terminals 2 and 3, supporting fast switching with minimal overvoltage.

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 ensures safe system behavior under fault conditions.
• Low stray inductance design mitigates over-voltage protection requirements and allows maximum voltage utilization.
• Robust thermal management via copper baseplate and aluminum nitride insulator reduces cooling requirements.

Applications

• High-frequency resonant converters and inverters
• Solar and wind inverters
• Uninterruptible power supplies (UPS) and switch-mode power supplies (SMPS)
• Motor drive systems
• Traction applications

Procurement Notes

Verify component authenticity through authorized Wolfspeed distributors or direct channels. Confirm datasheet revision status, as specifications may update without notice. Ensure proper handling procedures are followed due to the sensitivity of silicon carbide devices. Cross-reference part markings against official documentation to prevent counterfeit risks during acquisition.

Selection Notes

Select this module when transitioning from IGBT-based designs to improve efficiency and power density within standard 62 mm footprints. Consider the 1700 V rating for medium-voltage systems requiring robust blocking capability. Evaluate thermal resistance values against heatsink capabilities to ensure junction temperatures remain within the -40 °C to 150 °C operational range under expected load conditions.

Part Context

This component belongs to Wolfspeed's 62 mm BM platform series, which maintains compatibility with existing IGBT mechanical layouts. It shares the physical dimensions and terminal configuration with other modules in the family, facilitating easier design integration. The series targets industrial, traction, and renewable energy markets seeking reduced system size and cost through advanced SiC technology.

Replacement Considerations

Direct pin-to-pin replacements within the same 62 mm form factor include CAB320M17XM3, CAB400M12XM3, and CAS380M17HM3. Verify electrical parameters such as RDS(on) and VDS ratings before substitution, as performance characteristics vary across the product line. Mechanical mounting torque must remain at 5.0 N-m for all compatible variants.
