STH12N120K5-2AG

STH12N120K5-2AG is a high-performance N-channel power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in high-voltage environments. The device features a maximum drain-source voltage (VDS) of 1200 V, making it suitable for industrial and automotive power systems where robust voltage handling is essential. It offers a low on-resistance (RDS(on)) of typically 1.4 Ω at VGS = 10 V, ensuring minimal conduction losses and high energy efficiency during operation. This MOSFET utilizes advanced trench technology to optimize gate charge (Qg) and reduce switching losses, enabling faster switching speeds and improved thermal performance. Its gate threshold voltage (VGS(th)) ranges from 3 to 5 V, allowing compatibility with standard logic-level drivers while maintaining stable turn-on behavior. The device is characterized by a high avalanche energy rating, enhancing reliability under transient overvoltage conditions such as those found in motor drives or power supplies. The STH12N120K5-2AG is packaged in a TO-247-3L configuration, which provides excellent thermal dissipation through a directly connected tab to the PCB. This design supports reliable operation in demanding environments, including continuous operation at elevated temperatures up to 150°C junction temperature. Additionally, the component is fully compliant with AEC-Q101 standards, making it ideal for automotive applications such as DC-DC converters, battery management systems, and onboard chargers. Its primary function includes efficient switching in high-voltage DC-DC converters, inverters, and industrial motor control systems. The device excels in applications requiring high reliability, compact footprint, and low power loss, such as renewable energy systems (e.g., solar inverters), electric vehicle powertrains, and uninterruptible power supplies (UPS). The integrated body diode ensures safe freewheeling current paths in inductive load circuits, further simplifying system design. Engineered for durability and consistent performance, the STH12N120K5-2AG delivers exceptional ruggedness against electrostatic discharge (ESD) and surge events, reducing system downtime and maintenance costs. Its optimized RDS(on) × Qg product makes it particularly effective in reducing total switching and conduction losses, contributing to higher overall system efficiency. This combination of performance metrics and robust packaging positions the STH12N120K5-2AG as a preferred solution for engineers seeking reliable, high-efficiency power conversion in modern electronic systems.
