TLP5214A newly integrates such features as desaturation leading edge blanking time, filtering time, and optimization of soft turn-off performance. These contribute to secure execution of applications by suppressing short-time pulse noise during switching and desaturation sensing.

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 “Market Share: Semiconductor Devices and Applications Worldwide 2016” 30 March, 2016)

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.
