JSAB : Johnny Sin And Buddies

JSAB Technologies Limited is a high-tech company specializing in the R&D, design and sales of power semiconductor components. It is led by the professor of Hong Kong University of Science and Technology, and the only IEEE Fellow engaged in silicon-based power semiconductor research in Greater China. The company won the excellent enterprise award of the national competition, and the fourth place in the category of "new generation information technology" industry in Guangdong Province in the 2020 China Innovation and entrepreneurship competition.

JSAB Technologies has three mature product lines: low-voltage SGT-MOSFET (Split Gate Metal Oxide Semiconductor Field Effect Transistor), high-voltage SJ-MOSFET (Super Junction Metal Semiconductor Oxide Field Effect Transistor) and trench Field-stop IGBT (Insulated Gate Bipolar Transistor).  The high voltage products are mainly applied in high-speed rail, electric vehicles, new energy, industrial control and other fields. The low voltage products are mainly used in 5G base stations, power conversion, green household appliances, consumer electronics and so on. The products of JSAB Technologies have been recognized by many application customers and have been running stably in many fields.

Over the years, JSAB Technologies aims to become the leading power semiconductor enterprise with the advanced technology in Greater China, focusing on the R&D, design and sales of power semiconductor products. While insisting on creating long-term value for the society, JSAB Technologies also pursues growth unswervingly, makes unremitting efforts to promote innovation and responds to every challenge actively.
