Infineon T560N14TOF: A High-Performance 1400V IGBT for Demanding Power Conversion Applications

The relentless pursuit of higher efficiency, power density, and reliability in power electronics drives the continuous evolution of semiconductor technology. At the forefront of this innovation for high-voltage applications is the Infineon T560N14TOF, a 1400V IGBT that sets a new benchmark for performance in demanding power conversion systems.

Engineered to excel in rugged environments, this IGBT is a cornerstone for applications ranging from industrial motor drives and renewable energy inverters to uninterruptible power supplies (UPS) and traction systems. Its high voltage rating of 1400V provides a critical safety margin, ensuring robust operation and enhanced durability in circuits with fluctuating DC-link voltages, such as those found in three-phase systems operating off 690V mains.

The standout feature of the T560N14TOF is its exceptional low VCE(sat) of 2.15V (typical at 25°C). This low on-state voltage directly translates to reduced conduction losses, which is paramount for achieving high energy efficiency. Lower losses mean less heat generated within the system, allowing for simpler thermal management designs, reduced cooling requirements, and ultimately, higher power density. This efficiency is maintained across a wide operating temperature range, ensuring consistent performance even under strenuous conditions.

Furthermore, this device leverages Infineon's advanced Trenchstop™ and Fieldstop™ technologies. This combination optimizes the trade-off between saturation voltage and switching losses. The result is not only low conduction loss but also improved switching characteristics, leading to lower turn-off losses (Eoff). This is crucial for high-frequency switching applications, as it minimizes overall power dissipation and enables designers to push the boundaries of switching frequency for smaller magnetic components.

The robust short-circuit ruggedness (SCSOA) of the T560N14TOF ensures operational safety in fault conditions, a non-negotiable requirement in industrial and energy settings. Its positive temperature coefficient also simplifies the paralleling of multiple devices for higher power output, providing design flexibility and scalability.

ICGOOODFIND: The Infineon T560N14TOF emerges as a superior 1400V IGBT solution, masterfully balancing low conduction loss, robust switching performance, and inherent ruggedness. It is an ideal power semiconductor for engineers designing next-generation high-power systems where efficiency, reliability, and power density are the primary objectives.
