UF4SC120023B7S

UF4SC120023B7S is a high-performance silicon carbide (SiC) Schottky barrier diode manufactured by onsemi, designed for demanding power conversion applications. It features a maximum blocking voltage of 1200 V and a continuous forward current rating of 4 A, making it suitable for high-efficiency, high-frequency switching in industrial and automotive systems. The device utilizes SiC technology to achieve significantly lower forward voltage drop compared to traditional silicon diodes, resulting in reduced conduction losses and improved thermal performance. This diode exhibits fast switching speeds due to its Schottky structure, which eliminates minority carrier storage effects typical of conventional rectifiers. Its low reverse recovery time and minimal switching losses enable operation at frequencies up to several hundred kHz, enhancing system efficiency in power supplies, inverters, and motor drives. Additionally, the UF4SC120023B7S offers excellent thermal stability, with a junction-to-case thermal resistance of approximately 1.5 °C/W, allowing efficient heat dissipation in compact designs. The component is packaged in a compact, surface-mount TO-220-3L format, providing reliable mechanical and electrical performance in space-constrained environments. It meets AEC-Q101 reliability standards, ensuring robustness under harsh conditions such as vibration, temperature cycling, and humidity exposure—critical for automotive and industrial applications. The device also includes built-in protection against electrostatic discharge (ESD), improving durability during handling and integration into PCB assemblies. Key applications include electric vehicle (EV) onboard chargers, solar inverters, industrial DC-DC converters, and server power supplies where efficiency, size reduction, and reliability are paramount. Its ability to operate at elevated temperatures—up to 150°C junction temperature—supports continuous operation in high-heat environments without derating. The low leakage current, especially at high temperatures, further contributes to energy savings and system longevity. In summary, the UF4SC120023B7S combines the advantages of SiC material with optimized design to deliver superior performance in modern power electronics. It enables engineers to build more efficient, compact, and durable systems across a broad range of industries.
