Infineon FP50R12N2T7: A Comprehensive Technical Overview of the 50A IGBT Module

The Infineon FP50R12N2T7 represents a pinnacle of power semiconductor engineering, designed to meet the rigorous demands of high-power switching applications. This 1200V, 50A IGBT module integrates advanced technologies to deliver superior performance, reliability, and efficiency in industrial drives, renewable energy systems, and traction applications.

Core Architecture and Technology

At the heart of this module is Infineon’s proprietary TrenchStop™ IGBT technology. This design minimizes saturation voltage (Vce(sat)) and reduces switching losses, enhancing overall efficiency. The module incorporates a six-pack configuration (three-phase bridge), integrating six IGBTs and their corresponding antiparallel diodes in a single compact package. This integration simplifies system design, reduces external component count, and improves power density.

Electrical Characteristics and Performance

The FP50R12N2T7 is rated for a maximum collector-emitter voltage of 1200V and a nominal collector current of 50A at 80°C. Its low Vce(sat) of 1.65V (typical) ensures minimal conduction losses, which is critical for high-efficiency operation. The module features low switching losses, enabled by the optimized IGBT cell structure and fast soft-recovery Emitter Controlled diodes. This combination allows for higher switching frequencies, reducing the size of passive components like inductors and capacitors.

Thermal management is addressed through an low thermal resistance baseplate, facilitating effective heat dissipation. The module operates reliably over a junction temperature range of -40°C to +150°C, making it suitable for harsh environments.

Robustness and Reliability

Designed for longevity, the module boasts high short-circuit ruggedness (tSC = 10µs), providing critical protection in fault conditions. The use of AL2O3 ceramic substrates with copper metallization ensures excellent electrical isolation and thermal cycling capability. Moreover, the press-fit pin contacts offer robust mechanical connections, reducing soldering-related failures and simplifying assembly.

Application Focus

The FP50R12N2T7 is ideal for three-phase inverters in motor drives, UPS systems, and solar inverters. Its balanced performance characteristics make it a preferred choice for applications demanding high efficiency, compact size, and operational reliability.
