STTH512FP Description

Short technical summary and product information.

The STTH512FP is a fast recovery rectifier diode designed for high-voltage applications. It has a maximum repetitive reverse voltage of 1.2kV and an average forward current of 5A. The diode exhibits a typical forward voltage of 2.2V at 5A and a reverse recovery time of 95ns, making it suitable for high-frequency switching circuits. The device is housed in a TO-220 Full Pack isolated tab package (TO-220FPAC) with through-hole mounting, providing electrical isolation and ease of heat sinking. The operating junction temperature range extends up to 175°C. This component is RoHS3 compliant and has an MSL of 1 (unlimited). It is commonly used in power supplies, inverters, and motor control circuits where fast switching and high voltage capability are required.
