What Prisemi Electronics does

Prisemi Electronics (芯导科技) is a Shanghai-headquartered analog and power semiconductor company founded in 2009 and listed on the Shanghai Stock Exchange Science and Technology Innovation Board (STAR Market) under stock code 688230.SH since December 1, 2021. The company designs, develops, and sells two primary product lines: power devices (ESD/EOS protection, TVS, Zener, TSS, GDT, PTC fuses, medium/low and high-voltage MOSFETs, GaN HEMT, GaN Driver ICs, SiC SBD, SiC MOSFET, IGBTs, Schottky diodes, bridge rectifiers, and small signal transistors) and power ICs (lithium battery charging ICs, OVP protection ICs, load switches, audio power amplifiers, and DC/DC converters). Its portfolio spans 2,500+ product models, with notable proprietary technology in ultra-miniature packaging (DFN0603, CSP0603) and direct-drive GaN power ICs (PDG7115 series) achieving up to 50% power reduction versus traditional dual-MOS approaches.

The company generates revenue through hardware sales of these components to consumer electronics, automotive, industrial, communications, and power supply customers. Its go-to-market combines direct sales to major OEM brands (Xiaomi, Samsung, Transsion, OPPO, vivo, Honor, NIO, Anker, Lenovo moto, Meizu, UGREEN, Edifier, TCL) with an authorized distributor/agent network across China. End-market applications span mobile terminals (smartphones, tablets, TWS earphones, laptops, wearables), smart automotive (in-vehicle networks, lighting, intelligent seats), industrial (photovoltaic inverters, energy storage, BMS, EV charging, power tools), communications infrastructure (gateways, routers), and PD fast chargers/adapters. The company ships 8+ billion units annually to 3,000+ customers globally, with products exported to Europe, Americas, Japan, South Korea, and Southeast Asia. Operations span four Chinese locations (Shanghai HQ, Shenzhen regional office, Wuxi subsidiary, Xi'an R&D Center), with a Beijing-based optoelectronic integration investment fund as a portfolio holding.
