The STTH12012TV1 with Rectifiers high voltage diode is a semiconductor component manufactured by STMicroelectronics. It is a single-phase high-voltage power rectifier diode with a maximum repetitive peak reverse voltage of 1200 V and a maximum average forward current of 12 A. The diode provides a very low forward voltage drop, allowing for a highly efficient rectification process. The device also has a surge current rating up to 90 A. Its fast recovery time of 20 ns helps reduce conduction losses and minimize the effects of high-frequency ripple. This diode is ideally suited for high-frequency motor drives, welding machines, frequency converters, soft starters, inductive heating systems, and other industrial applications.
