Infineon IMZ120R030M1H: A 1200V 30mΩ SiC Trench MOSFET for High-Efficiency Power Conversion
The relentless pursuit of higher efficiency, greater power density, and improved reliability in power electronics is driving the rapid adoption of Wide Bandgap (WBG) semiconductors. Among these, Silicon Carbide (SiC) MOSFETs stand out for their superior material properties, enabling a paradigm shift in power conversion systems. The Infineon IMZ120R030M1H exemplifies this technological advancement, representing a state-of-the-art 1200V SiC MOSFET that sets a new benchmark for performance in demanding applications.
This device is engineered around a advanced Trench MOSFET structure. Unlike planar SiC MOSFET designs, the trench architecture places the gate electrode vertically within the silicon carbide. This pivotal design minimizes on-state resistance (RDS(on)) per unit area and significantly enhances channel mobility. The result is a remarkably low typical RDS(on) of just 30 mΩ at a 15V gate drive, which directly translates to reduced conduction losses. This efficiency gain is crucial for applications operating at high continuous currents, as it minimizes heat generation and improves overall system energy efficiency.
Beyond its impressive conduction characteristics, the IMZ120R030M1H excels in dynamic performance. The inherent advantages of SiC material allow for extremely fast switching speeds. This capability drastically reduces switching losses, which are a dominant loss factor in high-frequency operation. Designers can leverage this to push switching frequencies significantly higher than what is possible with silicon-based IGBTs or MOSFETs. Operating at higher frequencies allows for the use of smaller, lighter passive components like inductors and capacitors, leading to a substantial increase in overall power density and a reduction in system size and weight.
Furthermore, the robust 1200V voltage rating provides ample margin for operation in 800V bus architectures, which are becoming standard in electric vehicle (EV) powertrains, industrial motor drives, and renewable energy systems like solar inverters and energy storage. This high breakdown voltage ensures reliable operation under voltage spikes and harsh conditions. The device also features an integrated fast body diode with excellent reverse recovery characteristics, further minimizing losses in hard-switching topologies like boost converters and power factor correction (PFC) stages.
The combination of low conduction loss, minimal switching loss, and high-temperature operability makes the IMZ120R030M1H an ideal choice for the most demanding modern power conversion challenges. It is particularly suited for applications such as:
Electric Vehicle (EV) powertrains and on-board chargers (OBC).
Solar inverters and energy storage systems (ESS).
Industrial SMPS and server power supplies.
Uninterruptible Power Supplies (UPS).
Charging infrastructure for electric vehicles.
