Jiejie Microelectronics, established in 1995, is a high-tech enterprise integrating power semiconductor devices, power integrated circuits, chip R&D and manufacturing of new components, device R&D and packaging and testing, chip and device sales and services. The earliest domestic manufacturer of square bidirectional thyristors is also one of the professional manufacturers with the most complete varieties of single and bidirectional thyristors in China, making contributions to the localization of power semiconductor devices. 

The leading products are thyristors (single and bidirectional thyristors), MOSFETs (SGT, trench, planar, super-junction and other processes), low-junction capacitance discharge tubes and other protection devices, high-voltage rectifier diodes, and power switching transistors.
