Segment Reporting [Abstract] |
Segment Information | Segment Information The Company’s Chief Executive Officer functions as the chief operating decision maker ("CODM"). The CODM makes operating decisions and assesses performance based on the Company's major product lines, which represent its operating segments. The Company has three operating segments—Signal Integrity, Wireless and Sensing, and Protection—that historically had been aggregated into one reportable segment identified as the "Semiconductor Products Group." In the fourth quarter of fiscal year 2022, the Company updated its forecasts and assessed the economic performance of the three operating segments and concluded that Protection is no longer expected to be economically similar to the other operating segments. This is primarily because the Company's projections indicate that the gross margin of products within Protection will not be economically similar to products within the other operating segments. Accordingly, the Company concluded that Protection should be separately reported as its own reportable segment. This decision resulted in the formation of two reportable segments, including the High-Performance Analog Group, which is comprised of the Signal Integrity and Wireless and Sensing operating segments, and the System Protection Group, which is comprised of the Protection operating segment. All prior year information in the tables below has been revised retrospectively to reflect the changes to the Company's reportable segments. The Company’s assets are commingled among the three operating segments and the CODM does not use asset information in making operating decisions or assessing performance. Therefore, the Company has not included asset information by reportable segment in the segment disclosures below. Net sales and gross profit by segment were as follows:

Generally, the Company does not have long-term contracts with its distributors and most distributor agreements can be terminated by either party with short notice. For the third quarter of fiscal year 2023, the Company's largest distributors were based in Asia. Geographic Information Net sales activity by geographic region was as follows:
