Segment Reporting [Abstract]

Disaggregation of Revenue

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:

									Three Months Ended September 30,

									(in thousands)
Hong Kong															$	153,495					$	141,206

United States															1,073						1,395
Other countries															5,774						6,102
