Infineon AIMW120R045M1: A 1200V SiC MOSFET Power Module for High-Performance Applications

The relentless pursuit of higher efficiency, greater power density, and improved reliability in power electronics is driving the widespread adoption of wide-bandgap semiconductors. At the forefront of this revolution is silicon carbide (SiC), and Infineon Technologies is a key player with its extensive portfolio. The AIMW120R045M1 power module stands as a prime example, engineered to meet the demanding requirements of modern high-performance applications.

This module integrates a half-bridge configuration of state-of-the-art 1200V SiC MOSFETs, boasting an impressively low typical on-state resistance (R_DS(on)) of just 45 mΩ. This low resistance is a critical factor, as it directly translates to reduced conduction losses. When combined with the inherent advantages of SiC technology—such as negligible reverse recovery charge and the ability to operate at significantly higher switching frequencies than silicon-based IGBTs—the result is a substantial leap in system efficiency. This enables designers to create systems that are not only more powerful but also cooler running and more compact.

The AIMW120R045M1 is particularly suited for a range of demanding applications. It is an ideal candidate for the next generation of electric vehicle (EV) powertrains and fast-charging infrastructure, where efficiency and power density are paramount for extending range and reducing charging times. Furthermore, it finds a perfect home in industrial motor drives and renewable energy systems, such as solar inverters and energy storage solutions, where its high-voltage capability and robust performance ensure reliable operation in harsh environments.

The module utilizes the industry-standard 62mm housing, making it a form-factor-compatible drop-in upgrade for many existing systems designed with older IGBT technology. This allows for a straightforward design migration path, enabling engineers to achieve immediate performance gains without a complete system redesign. The package is designed for low stray inductance and offers a temperature range up to 150°C, supporting operation under strenuous conditions.
