UF3SC120040B7S
UF3SC120040B7S is a high-performance silicon carbide (SiC) trench MOSFET manufactured by onsemi, designed for efficient power conversion in demanding applications. It features a 1200 V blocking voltage, enabling operation in high-voltage systems such as industrial motor drives, renewable energy inverters, and electric vehicle (EV) chargers. The device offers a low on-state resistance of 40 mΩ, minimizing conduction losses and improving system efficiency, particularly at high currents.
This MOSFET utilizes a trench gate structure that enhances current handling capability while reducing switching losses compared to traditional planar designs. Its optimized layout ensures excellent thermal performance, allowing efficient heat dissipation and reliable operation under continuous load conditions. The device is rated for a maximum junction temperature of 175°C, making it suitable for harsh environments where thermal stability is critical.
The UF3SC120040B7S incorporates advanced SiC technology, which provides superior material properties such as higher breakdown field strength, better thermal conductivity, and lower leakage current than conventional silicon-based devices. These characteristics enable faster switching speeds—typically in the range of tens of nanoseconds—reducing electromagnetic interference (EMI) and enabling higher-frequency operation in power converters.
It is packaged in a TO-247-3L configuration, offering robust mechanical reliability and ease of integration into existing PCB layouts. The package includes an exposed die pad for improved thermal management and reduced thermal resistance between the junction and ambient environment. This design supports high-power density applications where space and thermal constraints are limiting factors.
Applications include medium- to high-power DC-DC converters, solar inverters, traction inverters for EVs, and industrial power supplies requiring high efficiency and compact form factors. The device’s compatibility with standard drive voltages (e.g., 15 V gate drive) simplifies system integration without the need for specialized driver circuits.
In summary, the UF3SC120040B7S delivers exceptional performance in high-voltage, high-efficiency power electronics, combining SiC advantages with a mature packaging solution tailored for modern energy-efficient systems.
