STD60NF55LAT4

The STD60NF55LAT4 is a high-performance N-channel Power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in power management systems. It features a maximum drain-source voltage (VDS) of 550 V, making it suitable for high-voltage circuits such as industrial motor drives, power supplies, and inverters. The device offers a low on-resistance of typically 135 mΩ at VGS = 10 V, ensuring minimal conduction losses and high energy efficiency. This MOSFET utilizes a trench technology structure that enhances gate charge performance and reduces switching losses, enabling faster switching speeds compared to conventional planar designs. With a continuous drain current (ID) rating of up to 60 A at 25°C junction temperature, the STD60NF55LAT4 delivers robust performance under demanding thermal conditions. Its optimized RDS(on) × Qg product makes it ideal for applications requiring both low conduction and switching losses. The device includes a built-in body diode with fast recovery characteristics, allowing for safe operation during freewheeling or flyback conditions. It also supports a wide gate drive voltage range from ±20 V, providing flexibility in driver circuit design while maintaining reliable operation. The TO-220AB package ensures good thermal dissipation and mechanical robustness, suitable for high-reliability industrial and automotive environments. Applications include AC/DC and DC/DC converters, solar inverters, uninterruptible power supplies (UPS), and industrial motor control systems. Its rugged construction and comprehensive protection against overcurrent, overtemperature, and avalanche breakdown make it well-suited for harsh operating conditions. The STD60NF55LAT4 complies with RoHS standards and is fully compatible with standard PCB assembly processes, supporting automated manufacturing and reducing production complexity.
