Segment Reporting [Abstract]  
Segment and Geographic Information Segment and Geographic Information
The Company is organized as, and operates in, one operating segment: the design, development and supply of power semiconductor products for computing, consumer electronics, communication and industrial applications. The chief operating decision-makers are the Executive Chairman and the Chief Executive Officer. The financial information presented to the Company’s Executive Chairman and Chief Executive Officer is on a consolidated basis, accompanied by information about revenue by customer and geographic region, for purposes of evaluating financial performance and allocating resources. The Company has one business segment, and there are no segment managers who are held accountable for operations, operating results and plans for products or components below the consolidated unit level. Accordingly, the Company reports as a single operating segment.

The Company sells its products primarily to distributors in the Asia Pacific region, who in turn sell these products to end customers. Because the Company’s distributors sell their products to end customers which may have a global presence, revenue by geographical location is not necessarily representative of the geographical distribution of sales to end user markets.

In February 2023, the Company entered into a license agreement with a customer to license the Company’s proprietary SiC technology and to provide 24-month engineering and development services for a total fee of $45 million.

The revenue by geographical location in the following tables is based on the country or region in which the products were shipped to:
