The Formosa MUR1060CT with old batch TO-220AB RoHS is an ultrafast rectifier. It is a silicon epitaxial-base planar device designed to be used in high-frequency, high-power switching applications such as switching power supplies, inverters, converters, audio amplifiers, and motor-controls. This device features low forward voltage and ultrafast switching speeds, making it ideal for applications that require high efficiency and high speed switching. It has an average forward current rating of 10A and a maximum peak repetitive reverse current of 5A at 14V. The MUR1060CT is RoHS compliant, so it does not contain hazardous substances such as lead, cadmium, mercury, hexavalent chromium, and polybrominated biphenyls or polybrominated diphenyl ethers.
