Company Introduction

Headquartered in Chengdu, China and founded in 2008, ARK (ARK Microelectronics

Co., Ltd.) is specializing in the research, design, manufacture, and marketing of power

semiconductor devices, and providing power management and circuit protection

solutions. It is the only company focusing on the design of Depletion-mode

MOSFETs in China. ARK can also provide customized development and manufacture

according to customer’s specific requirements. From design to manufacture to

post-sale service to products upgrade ARK provides full life cycle services of all its

products.

ARK's mission and practice is to drive innovation and R & D with market demand

and guide applications upgrade with technology development. Our products are

widely used in Charger, LED, industrial control, EV, communication circuit, Internet

of things and other fields.

The founders of the company have many years of R & D and management experience

in the semiconductor industry. The design team includes talents from both abroad and

domestic who hold PhD or MS degrees in EE from top universities and has close

co-operations with overseas R & D teams. ARK has the full ownership of all its

products and holds relevant invention patents. It is an original semiconductor

manufacturer, and its core competitiveness is strong R & D ability.

ARK has two product pipelines: industrial product series and consumer product

series.

Industrial series such as DMX

4022E, DMZ1511E, DMD4523E

are widely used in industrial control, EV, IOT and other fields. Depletion-mode

MOSFETs, unlike regular Enhancement-mode MOSFETs, require a negative gate

bias to turn off. They are suitable for Level shifting, Solid State Relays, Current

Regulators and Active loads. It replaces JFETs in traditional circuits with better

functions and features and is especially suitable for transient surge suppression and

over-voltage and over-current protection of high-voltage and high-current circuits.

The products meet the requirements of wide temperature range, high protection level,

high vibration resistance, etc., and comply with AEC-Q101 standard. The products

performance is on a par with similar foreign products, and can be widely used in new

energy fields such as EV, Charging Piles, Photovoltaics, Energy Storage, Rail Transit

System, etc..
