CAB004M12GM4

Overview

The Wolfspeed CAB004M12GM4 is a 1200 V, half-bridge silicon carbide (SiC) power module utilizing Gen4 technology. It features press-fit pins for assembly and offers an optional pre-applied thermal interface material. The module provides a maximum drain-source voltage of 1200 V and a continuous drain current of 200 A at a heatsink temperature of 50 °C. The typical on-state resistance is 4 mΩ at 25 °C, rising to 7.2 mΩ at 175 °C. Operating junction temperatures range from -40 °C to 150 °C continuously, with intermittent operation up to 175 °C. The package includes an integrated NTC temperature sensor and supports UL 1557 certification.

Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number CAB004M12GM4 indicates the module without pre-applied phase change thermal interface material. The variant ending in T, CAB004M12GM4T, includes the pre-applied thermal interface material. Confirm the required version matches the system's thermal management design before procurement.

Selection Notes

Select this module for applications requiring high efficiency and compact form factors due to low parasitic inductance and superior thermal performance. Ensure the gate driver supports the recommended operational gate voltage of 15 V with ±5% regulation tolerance. Verify that the system's stray inductance and heatsink temperature constraints align with the module's pulsed current and power dissipation limits.

Part Context

This component belongs to the WolfPACK™ industrial series of discrete semiconductor modules. It utilizes a standardized industry footprint designed for scalability across various power levels. The GM4 designation refers to the specific package style within the WolfPACK lineup, optimized for robust mounting and efficient heat transfer in demanding industrial environments.

Replacement Considerations

Direct replacements must match the 1200 V rating, half-bridge configuration, and compatible physical dimensions. Evaluate alternative modules based on comparable on-resistance values and thermal impedance characteristics. Ensure any substitute maintains similar switching speed capabilities and gate drive requirements to preserve system stability.

FAQ

What is the difference between CAB004M12GM4 and CAB004M12GM4T?

The primary difference is the inclusion of pre-applied phase change thermal interface material. The CAB004M12GM4T variant comes with this material applied, while the standard CAB004M12GM4 does not.

What is the maximum operating junction temperature?

The module supports continuous operation up to 150 °C. Intermittent operation is permitted up to 175 °C, though this may reduce the device lifespan.

How is the module mounted to the heatsink?

The module uses press-fit pins for assembly. It requires M4 bolts with a specified mounting torque of 2.0 to 2.3 N-m for secure installation.
