ARK (Ark Micro) was founded in 2008 and is the only company in China that focuses on the design of depletion MOSFETs. The product provides outstanding power processing and power management capabilities in an integrated control manner. The independently developed depletion MOSFET, SiC FET, optical relay, IC integrated power devices and other series of products are widely used in fields such as fast charging, LED, industrial control, electric vehicles, communication circuits, Internet of Things, photovoltaics, server power supply and charging piles.

The founder of the company has many years of experience in research and management in the semiconductor industry, and the team includes overseas returnees with doctoral degrees, top domestic university masters, and overseas R&D cooperation teams. Most of the R&D personnel have more than ten years of experience in the power semiconductor industry. All products are independently developed, and related technologies have obtained invention patents. Currently, the company has nearly 70 invention patents and integrated circuit layouts, and is a semiconductor manufacturer with independent research and development as its core competitiveness.

ARK's products can directly replace devices from Infineon, IXYS, Microchip, and other companies, such as DN3545, DN2540, DN2530, LND150N8, BSS169, BSS159, BSS139, BSS129, IRF6216, CPC3909, CPC5602, IXTA6N50D2, IXTY1N6R100D2, TC6320, etc. ARK (Ark Micro) can provide customized development services for devices with special parameters according to customer needs, such as PMOS, N+P dual channel MOS, medium voltage high resistance MOS, etc.

ARK (Ark Micro) products include two product lines, industrial and consumer, with independently developed DMMOS ® Series products, BVDSX from 60V-1200V; RDS (ON) ranges from 0.3 Ω to 700 Ω, covering the entire range of depletion MOSFETs.

The product is benchmarked against similar foreign products with high quality, high performance, and low cost, achieving domestic substitution and being recognized and widely adopted by domestic and foreign customers.
