Integration of a high-power infrared LED and high-gain/high-speed integrated circuit photo IC chip cuts power consumption to below a quarter that of Toshiba’s current output type ICs (TLX9304, TLX9376, TLX9378) and will reduce consumption during standby and driving of automotive applications.


The latest Gartner market report recognizes Toshiba as the leading manufacturer of optocouplers by sales in 2015 and 2016, with 23% of sale-based market share in CY2016. (Source: Gartner, Inc. “Market Share: Semiconductor Devices and Applications, Worldwide, 2016” 30 March 2017)


Toshiba will continue to deliver products that meet the needs of customers by promoting the development of a diverse portfolio of photocouplers and photorelays tailored to market trends.
