Infineon IGW30N100T: A High-Performance IGBT for Power Switching Applications
The demand for efficient and reliable power switching solutions continues to grow across industries such as industrial motor drives, renewable energy systems, and uninterruptible power supplies (UPS). At the heart of many of these applications lies the Insulated Gate Bipolar Transistor (IGBT), a key component that combines the simple gate drive characteristics of a MOSFET with the high-current and low-saturation-voltage capability of a bipolar transistor. The Infineon IGW30N100T stands out as a prime example of a high-performance IGBT engineered to meet these rigorous demands.
This device is a NPT (Non-Punch Through) trench IGBT, a technology that provides a superior trade-off between low conduction losses and minimal switching losses. Rated for a collector-emitter voltage of 1000 V and a continuous collector current of 45 A (at 100°C), the IGW30N100T is designed to handle significant power levels in various circuit topologies, including hard- and soft-switching inverters.

One of its most critical advantages is its low saturation voltage (VCE(sat)) of typically 2.3 V. This low on-state voltage directly translates into reduced conduction losses, leading to higher overall system efficiency and less heat generation. Furthermore, the device features positive temperature coefficient behavior, which simplifies the paralleling of multiple IGBTs for higher current applications, as it promotes an even distribution of current between the units.
The switching performance is equally impressive. The IGW30N100T offers fast switching speeds and includes a robust, co-packaged reverse recovery diode. This diode is optimized for softness and low reverse recovery charge, which is crucial for minimizing voltage overshoots and electromagnetic interference (EMI) in circuits like power factor correction (PFC) and motor control bridges. This integration enhances system reliability and simplifies circuit design and assembly.
To ensure operation in demanding environments, the IGBT is housed in a TO-247 package, renowned for its excellent thermal performance and mechanical robustness. This package allows for efficient heat dissipation away from the silicon die, enabling the device to operate at high junction temperatures while maintaining stability and longevity.
ICGOODFIND: The Infineon IGW30N100T is a robust and highly efficient 1000V IGBT that excels in power switching applications. Its combination of low conduction and switching losses, positive temperature coefficient for easy paralleling, and integrated ultra-soft diode make it an exceptional choice for designers seeking to optimize performance, reliability, and efficiency in high-power systems.
