Description

technical field [0001] The invention relates to the technical field of semiconductor components, in particular to an in-line rectifier bridge device with output protection. Background technique [0002] With the development of society, electronic products are becoming more and more sophisticated, and the requirements of electronic products for power supply are also getting higher and higher. When the existing AC power grid is struck by lightning and power equipment starts and stops, instantaneous interference will occur in the power grid, which will damage electronic equipment and circuits. Many electronic components that use direct current are used in electronic products, so it is necessary to add electronic components that convert AC to DC and have a rectification and voltage stabilization structure before connecting to the grid to protect these electronic components. Existing TVS diodes have extremely fast response times (nanoseconds) and relatively high surge absorption...
