SEMICONDUCTOR COMPONENT AND METHOD OF MANUFACTURE

摘要

In accordance with an embodiment, a semiconductor component includes a common mode filter monolithically integrated with a protection device. The common mode filter may be composed of first, second, third, and fourth coils, wherein each coil has first and second terminals and the first coil is magnetically coupled to the second coil and the third coil is magnetically coupled to the fourth coil. The protection device has a first terminal coupled to the first terminal of the first coil and a second terminal coupled to the first terminal of the third coil. An energy storage element has a terminal coupled to the second and first terminals of the first and second coils, respectively. Another embodiment includes monolithically integrating a common mode filter with a protection device and monolithically integrating a metal-insulator-metal capacitor with the common mode filter.
