CAB008A12GM3

Overview

The Wolfspeed CAB008A12GM3 is a baseplate-less, half-bridge silicon carbide (SiC) power module designed for medium-power applications. It features an 8 mΩ typical on-state resistance and a 1200 V drain-source voltage rating. The device utilizes press-fit pins for assembly and includes an integrated NTC thermistor for thermal monitoring. Key electrical parameters include a DC continuous drain current of 181 A at a heatsink temperature of 75 °C and a junction temperature limit of 150 °C. The module operates within a virtual junction temperature range of -40 °C to 150 °C, with intermittent operation allowed up to 175 °C.

Feature Summary

• Fully SiC MOSFET-based architecture providing ultra-low switching and conduction losses
• Zero turn-off tail current characteristic inherent to the MOSFET technology
• Aluminum nitride substrate for enhanced thermal conductivity
• Press-fit pin configuration enabling easy assembly and scalability

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 suffix when purchasing. The 'GM3' designation indicates the third-generation WolfPACK package. Confirm whether the standard part number requires separate application of thermal interface material or if the 'T' suffix variant with pre-applied phase change TIM is required for the design. Ensure compliance with UL 1557 certification requirements for electrically isolated semiconductor devices in the target system.

Selection Notes

Select this component based on its 1200 V blocking capability and low on-resistance for high-efficiency designs. Consider the 181 A continuous current rating relative to the expected heatsink temperature and duty cycle. Evaluate the need for the pre-applied thermal interface material option versus manual application. Verify that the operating junction temperature limits align with the thermal management strategy of the host equipment.

Part Context

This module belongs to the Wolfspeed WolfPACK family of baseplate-less power modules. The family offers various configurations including half-bridge, six-pack, full-bridge, and T-type topologies. These modules are engineered to increase efficiency and power density while reducing system size and weight compared to traditional discrete solutions.
