High-current photorelays for factory automation and other industrial applications that can replace mechanical relays: TLP3543A, etc.

Product News 2018-01

The package photograph of high-current photorelays for factory automation and other industrial applications that can replace mechanical relays: TLP3543A, etc.

All of five products including "TLP3543A" are high-current photorelays mounted with the state-of-the-art U-MOSVIII process MOSFET in a DIP4 or DIP6 package.
The new photorelays offer multiple options, with an OFF-state output terminal voltage ranging from 30 to 200 V and a steady ON-state current of 0.7 to 5.0 A. They can replace 1-Form-A mechanical relays in various DC and AC applications, contributing to improved system reliability and reducing the space needed for relays and relay drivers. They deliver a rated operating temperature of 110°C (max), making it easier to accommodate temperature margins in system designs. In addition, the new photorelays provide a rated transient ON-state current three times larger than the rated steady ON-state current, contributing to design safety.

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

Toshiba Electronic Devices & Storage Corporation will continue to develop products that meet the needs of customers by promoting the development of a diverse portfolio of photocouplers and photorelays tailored to market trends.
