STH2N120K5-2AG

STH2N120K5-2AG is a high-performance N-channel power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in industrial and consumer electronics. It features a maximum drain-source voltage (VDS) of 1200 V, making it suitable for high-voltage DC-DC converters, motor drives, and power supplies operating in demanding environments. The device exhibits a low on-state resistance (RDS(on)) of typically 3.5 Ω at VGS = 10 V, ensuring minimal conduction losses and high energy efficiency. The MOSFET is optimized for fast switching speeds, with a gate charge (Qg) of approximately 86 nC, enabling reduced switching losses and improved thermal performance in high-frequency applications. Its robust construction supports a continuous drain current (ID) of up to 2.5 A at 25°C junction temperature, while the avalanche energy rating allows safe operation under transient overvoltage conditions. The TO-220AB package provides reliable mechanical and thermal characteristics, facilitating easy integration into printed circuit boards and heat-sink mounting solutions. This component is particularly well-suited for use in photovoltaic inverters, electric vehicle chargers, and industrial servo drives where reliability, efficiency, and compact design are critical. Its built-in body diode offers reverse-current protection, enhancing system safety during commutation events. Additionally, the device complies with RoHS standards and is lead-free, aligning with environmentally responsible manufacturing practices. STMicroelectronics’ advanced trench technology ensures excellent gate threshold stability and low gate leakage current, contributing to long-term operational reliability. The STH2N120K5-2AG also demonstrates strong immunity to electromagnetic interference (EMI), making it ideal for noise-sensitive applications such as medical equipment and communication infrastructure. With its wide operating temperature range from -55°C to +150°C, it performs consistently across diverse environmental conditions, from cold outdoor installations to high-temperature industrial settings.
