CAB011A12GM3T

Overview

The Wolfspeed CAB011A12GM3T is a baseplate-less, half-bridge Silicon Carbide (SiC) power module featuring an Aluminum Nitride substrate. It provides a drain-source voltage of 1200 V and a typical on-state resistance of 11 mΩ at 25°C. The module supports a continuous drain current of 149 A at a heatsink temperature of 75°C with a virtual junction temperature limit of 175°C. It utilizes press-fit pins for assembly and includes an integrated NTC thermistor for thermal monitoring. The 'T' suffix indicates the inclusion of pre-applied phase change thermal interface material.

• Press-fit pin design facilitating easy assembly and system scalability
• Zero turn-off tail current characteristic inherent to MOSFET technology
• UL 1557 certified electrically isolated semiconductor device

Applications

• DC-DC Converters
• EV Chargers
• High-Efficiency Converters / Inverters
• Renewable Energy Systems
• Smart-Grid / Grid-Tied Distributed Generation

Procurement Notes

Verify the specific ordering code against the datasheet to ensure the presence of pre-applied thermal interface material, as indicated by the 'T' suffix in CAB011A12GM3T. Confirm that the application environment adheres to the specified operating temperature ranges and mounting torque requirements for M4 bolts. Ensure compatibility with recommended gate drive voltages and transient limits defined in the electrical specifications.

Selection Notes

Select this module for medium-power applications requiring high efficiency and compact form factors within industry-standard footprints. Consider the 18.3 nH stray inductance and 0.213 °C/W thermal resistance when designing the PCB layout and heatsinking. Evaluate the pulsed current capabilities and safe operating area curves for dynamic load conditions. Verify that the external gate resistor values align with the switching energy performance targets.

Part Context

This component belongs to the Wolfspeed WolfPACK family of baseplate-less modules designed for medium power applications. It shares the GM3 generation technology platform with other variants like the CAB011A12GM3, differing primarily in packaging configuration and thermal interface provisions. The series aims to reduce assembly overhead while maintaining high power density.

Replacement Considerations

The non-taped version CAB011A12GM3 serves as a direct functional substitute if pre-applied thermal interface material is not required. Other WolfPACK GM3 modules may offer alternative current ratings but require verification of pinout and thermal characteristics for mechanical compatibility.

FAQ

What is the difference between CAB011A12GM3 and CAB011A12GM3T?

The 'T' suffix indicates that the module comes with pre-applied phase change thermal interface material, whereas the standard version does not.

What is the maximum virtual junction temperature for intermittent operation?

The module supports a maximum virtual junction temperature of 175°C for intermittent operation, though this may result in reduced life expectancy.

How is the module mounted?

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