CAB008A12GM3T

Overview

The Wolfspeed CAB008A12GM3T is a baseplate-less, half-bridge Silicon Carbide (SiC) MOSFET module featuring an aluminum nitride substrate and pre-applied phase change thermal interface material. It provides a drain-source voltage of 1200 V and a typical on-state resistance of 8 mΩ at 25°C. The module supports a DC continuous drain current of 181 A at a heatsink temperature of 75°C with a junction temperature limit of 150°C, or 196 A at a junction temperature limit of 175°C. Operating within a virtual junction temperature range of -40°C to 175°C, it utilizes press-fit pins for assembly and includes an integrated NTC thermistor for thermal monitoring.

Feature Summary

• Fully SiC MOSFET-based architecture enabling ultra-low conduction and switching losses
• Zero turn-off tail current characteristic inherent to the MOSFET technology
• Aluminum nitride substrate providing high thermal conductivity and electrical isolation
• UL 1557 certified electrically isolated semiconductor device component

Applications

• DC-DC Converters
• Electric Vehicle (EV) Chargers
• High-Efficiency Converters and Inverters
• Renewable Energy Systems
• Smart-Grid and Grid-Tied Distributed Generation

Procurement Notes

Verify the specific ordering suffix 'T' to confirm the inclusion of pre-applied phase change thermal interface material, as this distinguishes the part from the non-pre-applied variant. Ensure compatibility with standard WolfPACK mounting requirements and verify that the selected gate driver board aligns with the module's electrical specifications before procurement.

Selection Notes

Select this module for applications requiring compact, industry-standard footprints with high power density. Consider the 8 mΩ on-resistance and low stray inductance for high-frequency operation. Evaluate the thermal management strategy based on the specified junction-to-heatsink thermal resistance and the maximum allowable junction temperatures for continuous versus intermittent operation.

Part Context

This component belongs to the Wolfspeed WolfPACK family of baseplate-less modules designed for medium-power applications. The WolfPACK series aims to increase system efficiency and reduce assembly overhead by offering scalable solutions across various configurations, including half-bridge, six-pack, and full-bridge topologies up to 3.3 kV.

Replacement Considerations

The CAB008A12GM3 serves as the direct functional equivalent without pre-applied thermal interface material. Verify mechanical fit and thermal performance differences when substituting between the T and non-T variants.
