Infineon IHW25N120R2: A High-Performance 1200V 25A IGBT for Advanced Power Switching Applications
The relentless pursuit of efficiency, power density, and reliability in modern power electronics drives the continuous innovation in semiconductor switching devices. Among these, the Insulated Gate Bipolar Transistor (IGBT) remains a cornerstone for medium to high-power applications. The Infineon IHW25N120R2 stands out as a prime example of this evolution, representing a high-performance 1200V, 25A IGBT engineered to meet the demanding requirements of advanced power conversion systems.
This device is built upon Infineon's robust and proven TrenchStop™ IGBT technology. This proprietary technology is pivotal to its superior performance. It creates a trench gate structure that optimizes the carrier concentration in the drift region, leading to a significantly reduced saturation voltage (VCE(sat)) compared to previous generations. The direct benefit of this is markedly lower conduction losses, which translates into higher efficiency and reduced heat generation within the system. For designers, this means the potential for smaller heatsinks, reduced cooling requirements, and ultimately, a more compact and cost-effective overall design.
Beyond low conduction losses, the IHW25N120R2 excels in its switching characteristics. It features an exceptionally soft and robust switching behavior, which is crucial for minimizing electromagnetic interference (EMI) and voltage overshoots across the device. This soft recovery is largely attributed to the co-packaged ultra-soft reverse recovery Emitter Controlled Diode. This diode works in tandem with the IGBT to ensure smooth commutation, enhancing the system's reliability and simplifying the design of snubber circuits. This makes the device particularly suitable for resonant switching topologies like LLC converters and applications operating at elevated switching frequencies.
The combination of a high voltage rating of 1200V and a collector current of 25A positions the IHW25N120R2 as an ideal solution for a wide array of industrial and commercial applications. It is a perfect fit for high-performance switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), solar inverters, and industrial motor drives. Its ability to operate efficiently and reliably under strenuous conditions makes it a preferred choice for engineers looking to push the boundaries of power density and performance.
Furthermore, the device offers excellent short-circuit ruggedness (SCSOA), providing a critical safety margin in fault conditions. This ruggedness, combined with a wide operating junction temperature range, ensures long-term operational stability and system durability.
ICGOODFIND: The Infineon IHW25N120R2 is a high-efficiency IGBT that leverages advanced TrenchStop™ technology to deliver an optimal balance of low conduction loss, soft switching, and high ruggedness.
