Infineon FS400R12A2T4: A High-Performance 1200V IGBT Power Module for Industrial Drives and Inverters

The relentless pursuit of efficiency, power density, and reliability in industrial automation and energy conversion has driven power semiconductor technology to new heights. At the forefront of this evolution is the Infineon FS400R12A2T4, a 1200V IGBT power module engineered to meet the demanding requirements of modern industrial motor drives, uninterruptible power supplies (UPS), and solar inverters.

This module integrates a robust and sophisticated architecture, centered on Infineon's advanced TrenchStop™ IGBT4 technology. This proprietary cell design is pivotal to the module's performance, significantly reducing both saturation voltage (Vce(sat)) and switching losses. The result is a remarkable boost in overall system efficiency, which translates directly into lower operational costs and reduced cooling requirements for end-users. The low-loss diode, also based on latest emitter-controlled technology, further minimizes reverse recovery losses, ensuring smooth and efficient operation during switching cycles.

Designed for high-power applications, the FS400R12A2T4 boasts a high nominal current rating of 400A, making it suitable for driving large industrial motors in the multi-kilowatt range. Its 1200V blocking voltage provides a crucial safety margin and robust performance in 690VAC industrial mains systems, ensuring stable operation even under voltage spikes and harsh grid conditions. The module's low-indunce design is another critical feature, which helps to suppress overvoltage peaks during turn-off, enhancing system reliability and protecting other components.

Beyond its electrical prowess, the module is built for durability. The utilization of AL2O3 (Alumina) ceramic substrates with Direct Copper Bonding (DCB) ensures excellent thermal cycling capability and high isolation strength. This robust construction allows the module to withstand the mechanical stress induced by frequent temperature swings, a common challenge in industrial environments. Paired with a low thermal resistance, this design enables efficient heat dissipation to an external heatsink, maintaining junction temperatures within safe operating limits.

The FS400R12A2T4 is offered in the industry-standard EconoDUAL™ 3 package. This familiar footprint simplifies mechanical integration and system design, allowing engineers to upgrade existing platforms or develop new ones with minimal redesign effort. The package includes auxiliary emitter terminals for precise gate control, which is essential for optimizing switching behavior and minimizing electromagnetic interference (EMI).

In summary, the Infineon FS400R12A2T4 stands as a benchmark for high-power conversion. It masterfully balances the critical trade-offs between low conduction loss, low switching loss, and high ruggedness, making it an ideal solution for next-generation industrial inverters and drives that demand uncompromising performance and long-term reliability.
