On March 26, 2021, the 2021 (Spring) USB PD&Type-C Asia Exhibition was successfully held at the Science and Technology Park in Nanshan District, Shenzhen. This exhibition brings together nearly a hundred high-quality suppliers and service providers in the industry chain, as well as thousands of buyers.
USB PD&Type-C Asia, along with APEC and PCIM, is known as the three major global power industry exhibitions. These three exhibitions have their own characteristics and user groups, attracting power companies and engineers from various fields around the world to attend.
Jiejie Microelectronics (booth number: E08) debuted at the exhibition with the latest low conduction resistance SGT MOSFET and AC/DC new production lines. There are many customers who come to the booth for consultation and negotiation.

Jiejie SGT MOSFET
Jiejie Microelectronics (Shanghai) Technology Co., Ltd. is a subsidiary of the listed Jiangsu Jiejie Microelectronics Group, located in the Lingang New Area of China (Shanghai) Pilot Free Trade Zone. Specializing in the design, process research and development, and sales of high-performance power semiconductor devices. The core team of Jiejie Shanghai is composed of the general manager of the business unit from internationally renowned semiconductor companies, top power device design engineers, and a group of senior experts in chip process, packaging technology, product engineering, quality management, and market sales. The engineering team continuously breaks through core technologies and gradually introduces advanced proprietary JSFETs ® Technical platform, SGT MOSFETs with a withstand voltage range of 30-150V, and no less than 22 technical patents have been applied for and passed. Combined with new power packaging technology, these SGT MOSFETs have achieved world-class performance and industry-leading electrical characteristics such as low conduction impedance and junction capacitance/load. They have been widely used by many world-renowned OEMs&ODMs in various terminals such as USB PD fast charging, AC/DC SMPS, motor drive, lithium battery protection, BMS, computers and peripherals, communication power supply, etc.
Because the fast charging market is still in its early stages of development, currently Jeje Microelectronics mainly focuses on the end markets of consumer, industrial, and automotive products below 150W. At present, Jiejie Shanghai has provided efficient and reliable SGT MOSFETs with voltage resistance from 30V to 150V, and SJ MOSFETs with voltage resistance of 650V or higher. At the same time, as a senior executive of the company has been involved in the development of multiple USB standards since 1994, and also participated in the standard negotiation during the drafting of the USB-C fast charging agreement that year, he has a deep understanding of the industry ecology and market acceptance process of fast charging. Therefore, Jiejie Shanghai is also coordinating with various subsidiaries of Jiejie Microelectronics Group to provide the main components used in the fast charging solution, such as the full bridge at the AC inlet, PFC and filter rectifier, primary power management IC, secondary synchronous control IC, fast charging protocol decoding IC, protective devices such as TVS and ESD.
Product recommendations
In response to fast charging chargers, Jiejie Microelectronics can mostly provide complete discrete device solutions. For example, AC input surge proof MOV, clamp transformer leakage inductance, and primary high-voltage MOSFET VDS_ Max produces overvoltage fast recovery rectifier tubes, primary PFC (design above 75W) and PWM high-voltage MOSFETs, secondary synchronous rectification, medium/low voltage MOSFETs for USB Type-A/C port output switches, ESD protection for USB Type-A/C port, etc.

For chargers compatible with fast charging protocols such as USB PD, Huawei FCP, MTK PE+, Qualcomm QC, etc., in the secondary synchronous rectifier switch circuit, Jiejie Microelectronics provides 60~150VDS from the following list_ Max SGT N-MOSFETs are selected by circuit design engineers.

In the switch circuit before the USB-C output interface, Jiejie Microelectronics provides the 30~40VDS listed below_ Max SGT N-MOSFETs are selected by circuit design engineers.

For applications such as AC/DC and DC/DC power conversion, wireless fast charging compatible with Qi electromagnetic induction or WPT electromagnetic resonance protocol, motor drive, mini LED backlight drive, battery protection and management, Jiejie Microelectronics provides 30-150VDS from the following list_ Max SGT N-MO
