CAB400M12XM3

Overview

The Wolfspeed CAB400M12XM3 is a Silicon Carbide (SiC) half-bridge module featuring third-generation MOSFET technology. It provides a drain-source voltage of 1200 V and supports continuous drain currents up to 405 A at 25 °C case temperature, with a pulsed current capability of 800 A. The typical on-state resistance is 4.0 mΩ at 15 V gate drive. Operating within a virtual junction temperature range of -40 °C to 175 °C, the device incorporates an isolated integrated NTC temperature sensor for thermal monitoring. The package utilizes a silicon nitride insulator and copper baseplate, achieving a low stray inductance design of 6.7 nH between terminals.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Wolfspeed documentation. Confirm that the received hardware matches the specified XM3 package dimensions and pinout configuration. Ensure compliance with RoHS directives as stated in the datasheet. Validate technical suitability through independent testing before deployment in critical systems.

Selection Notes

Select this module when designing systems requiring 1200 V blocking capability and high current handling up to 400 A. Consider the 175 °C maximum junction temperature rating for applications demanding elevated thermal operation. Evaluate the 6.7 nH internal stray inductance for high-speed switching requirements. Ensure the gate driver can accommodate the specified -4 V to +15 V operational voltage range.

Part Context

This component belongs to the Wolfspeed XM3 series of discrete semiconductor modules. It represents a specific iteration of their third-generation Silicon Carbide technology, designed to replace previous generations with improved switching performance and lower on-state resistance while maintaining the standard 62mm footprint form factor.

Replacement Considerations

Direct substitutes include the EAB450M12XM3 and CAB450M12XM3 from the same manufacturer family. These alternatives offer similar 1200 V ratings but feature higher current capacities of 450 A. Verify mechanical mounting compatibility and ensure gate drive parameters align with the specific electrical characteristics of the replacement unit.
