UL insulated thyristor products increase, for customers to choose more models

In order to ensure the electrical insulation level of electrical equipment, household appliances, industrial electrical appliances, etc., electronic components with their own electrical insulation capabilities have always been the primary choice in the hands of electrical designers. The electrical insulation grade requires that the semiconductor device have a high dielectric withstand strength and good heat resistance to avoid deterioration due to long-term overheating. We have always attached great importance to the development of insulated single thyristor devices. As early as 2005, the company designed and developed a variety of insulated devices, and passed the UL (Insurer Laboratories Underwriter Laboratories Inc.) 1557 electrical insulation. Standard test. In 2011, in order to meet the needs of more domestic and foreign customers for insulated single and two-way thyristors, the company will hand over thousands of models of TO-92, TO-220, TO-3P and TO-220F. UL laboratory test, after 2 months of severe sampling test (normal temperature 25 ° C and high temperature 219 ° C / 300 h), and finally passed the UL1557 electrical insulation type semiconductor device test requirements, obtained the UL authorization certificate.
