市场监管总局：我国牵头修订的两项功率半导体器件国际标准发布

Core Viewpoint - The International Electrotechnical Commission (IEC) has released two key international standards in the power semiconductor device sector, led by China, marking a significant breakthrough in China's participation in international standardization efforts for power semiconductor devices [1] Group 1: International Standards - The two revised international standards are "Semiconductor Devices - Part 2: Discrete Devices - Rectifier Diodes" (IEC60747-2:2025ED4.0) and "Semiconductor Devices - Part 6: Discrete Devices - Thyristors" (IEC60747-6:2025ED4.0) [1] - These standards address long-standing mismatches between technical content and product development, enhancing the applicability and operability of testing for high-power semiconductor devices [1] Group 2: Applications and Impact - Rectifier diodes and thyristors are fundamental semiconductor devices widely used in household appliances such as mobile phone chargers, lighting controls, vacuum cleaner speed regulation, and electromagnetic stove power control [1] - They are also extensively utilized in electric vehicles and charging stations, renewable energy generation, new power systems, smart grids, industrial automation, and aerospace [1] - The new standards will serve as important references for global manufacturers, users, and third-party testing organizations in product research, testing, and application, thereby improving the overall technology and quality level of China's power electronics industry [1] Group 3: Collaborative Efforts - Chinese experts, as project leaders, collaborated with specialists from Japan, Germany, and South Korea to discuss terminology, definitions, testing methods, and conditions within the standards [2] - The domestic technical team conducted over a thousand related experimental validations to ensure the standards are structurally rigorous and content-complete [2]
