Sansha Electric MFG. Co., Ltd. is engaged in the development, production and sales on two business segments: Power Supply equipment and Power semiconductors.
Power semiconductors are essential devices used to improve power efficiency and energy savings, by converting direct current to alternating current and precisely controlling the flow of current or the voltage increase and decrease.

By combining both technologies, we provide various power semiconductors for power equipment and a wide selection of industrial power equipment from small power to larger ones, leading the industry in both domestic and overseas markets.

Power Semiconductors Division

Large-capacity power module, small-capacity power discrete

Distinctive features

  • Development of high breakdown voltage and large current with low loss

    Unlike the planar-type chips currently mainstream in the semiconductor industry, we use a mesa structure chip that couples high breakdown voltage with low loss in the same chip.

  • Unique process and package technology for high reliability

    Our unique process and packaging technology has been highly evaluated in industrial applications where long-term reliability is required.
