TN4050HP-12GY-TR

TN4050HP-12GY-TR is a high-performance power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in modern electronic systems. It features a drain-source voltage rating of 60V and a continuous drain current of up to 50A at 25°C, making it suitable for high-current, low-voltage power conversion tasks. The device exhibits a very low on-resistance (RDS(on) = 3.5 mΩ max at VGS = 10V), which minimizes conduction losses and improves system efficiency—especially critical in energy-sensitive designs such as DC-DC converters and motor drives. This MOSFET is constructed using ST’s advanced TrenchMOS™ technology, enabling superior thermal performance and robustness under high-stress conditions. Its enhanced gate charge (QG = 78 nC typ.) ensures fast switching speeds with reduced switching losses, supporting operation at frequencies up to several hundred kHz. The device also includes an integrated body diode with low forward voltage drop, which facilitates freewheeling current paths in inductive load circuits without additional external components. Packaged in a TO-220-3L form factor, TN4050HP-12GY-TR offers excellent thermal dissipation through direct mounting on heatsinks, enhancing reliability in high-power environments. It is fully compliant with RoHS standards and designed for long-term operational stability under harsh industrial conditions, including wide temperature ranges from -55°C to +175°C junction temperature. The transistor is widely used in automotive power systems, such as electric power steering, battery management systems, and onboard chargers, where high efficiency, compact size, and reliability are essential. It also serves well in industrial automation equipment, consumer electronics like power supplies and LED drivers, and renewable energy inverters due to its ability to handle transient overloads and maintain consistent performance across varying loads. Its rugged design supports safe operation under short-circuit conditions, thanks to built-in avalanche capability and a protective structure that limits damage during fault events. This makes the TN4050HP-12GY-TR ideal for applications requiring high safety margins and minimal downtime. Additionally, its compatibility with standard driver circuits simplifies integration into existing PCB layouts without complex gate drive requirements.
