Infineon IMBF170R1K0M1XTMA1: 1700V SiC MOSFET for High-Efficiency Power Conversion
The global transition toward high-efficiency energy systems is accelerating, driven by demands for reduced carbon emissions and improved power density across industries such as renewable energy, industrial motor drives, and electric vehicle (EV) charging infrastructure. At the heart of this transformation are advanced semiconductor technologies that enable higher switching frequencies, lower losses, and greater thermal performance than traditional silicon-based devices. The Infineon IMBF170R1K0M1XTMA1, a 1700V silicon carbide (SiC) MOSFET, stands out as a pivotal solution designed to meet these rigorous requirements.
Built on Infineon’s cutting-edge SiC technology, this MOSFET delivers exceptional blocking voltage capability of 1700V, making it particularly suitable for high-voltage applications like solar inverters, energy storage systems, and industrial power supplies. The device’s high voltage rating allows designers to simplify circuit topologies by reducing the need for complex series-connection schemes often required with lower-voltage components. This not only enhances system reliability but also reduces overall component count and board space.
One of the most significant advantages of the IMBF170R1K0M1XTMA1 is its superior switching performance. Silicon carbide material properties enable faster switching speeds compared to conventional silicon MOSFETs or IGBTs. This results in drastically reduced switching losses, which is critical for improving efficiency in high-frequency power conversion systems. Lower losses also mean less heat generation, reducing the thermal management burden and enabling more compact, lightweight designs.
Moreover, the device features a low on-resistance (RDS(on)) of just 1000 mΩ (max), which minimizes conduction losses during operation. This characteristic ensures high energy efficiency even under heavy load conditions, contributing to overall system reliability and longevity. The combination of low RDS(on) and high switching performance makes this MOSFET ideal for applications demanding both high power and high frequency.

The IMBF170R1K0M1XTMA1 is offered in a robust TO-leadless (TOLL) package, which provides improved thermal resistance and power cycling capability. The package design enhances heat dissipation, allowing the device to operate at higher junction temperatures while maintaining performance. This is particularly beneficial in harsh environments where cooling may be challenging.
Furthermore, Infineon has optimized this MOSFET for ease of use, with integrated features such as a short-circuit withstand time and improved body diode reliability. These attributes ensure robust operation under fault conditions, enhancing system safety and reducing the need for external protection circuitry.
In renewable energy systems, such as photovoltaic inverters, the high voltage and efficiency of this SiC MOSFET enable higher DC input voltages, reducing cable costs and improving conversion efficiency. In EV charging stations, it supports faster switching frequencies, leading to smaller magnetics and more power-dense chargers. For industrial applications, it helps increase the efficiency of motor drives and UPS systems.
The Infineon IMBF170R1K0M1XTMA1 1700V SiC MOSFET is a high-performance semiconductor device that pushes the boundaries of power conversion technology. With its high voltage capability, low switching and conduction losses, and robust thermal performance, it is an excellent choice for designers seeking to build efficient, compact, and reliable high-power systems.
