STMICROELECTRONICS STTH208 High Voltage Rectifier

The STTH208 is an ultrafast high-voltage rectifier designed with planar technology, suitable for SMB applications like free-wheeling, clamping, and snubbering in power supplies. It features a maximum repetitive peak reverse voltage of 800 V, and an operating junction temperature up to 175°C. With low forward voltage drop around 1.25 V at 2 A, it ensures high efficiency and reliable operation. Its high surge current capability and soft switching reduce EMI disturbances, making it ideal for power switching and demagnetization applications.
