Power Semiconductor Switches are the discrete power device. A discrete power device (or discrete component) is an electronic component with just one circuit element, other than an integrated circuit. It is an electronic component widely used in automotive & transportation, industrial, consumer, communication and among others. The power transistors and thyristors are called Power Semiconductor Switches, which include PowerMOSFETs, IGBTs, Bipolar Power Transistors, SCR, GTO etc.
Global Power Semiconductor Switches main players are Infineon Technologies AG, ON Semiconductor, STMicroelectronics N.V., Toshiba Corporation, etc. Global top four manufacturers hold a share over 35%. China is the largest market, with a share nearly 50%.
