Toshiba Electronic Devices & Storage Corporation Adds New Line-up of High Speed Signal Transmission Photorelays with Industry's Smallest Footprint

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (TDSC) today announced the launch of two high speed signal transmission photorelays, “TLP3475S” and “TLP3440S,” that realize the industry’s smallest footprint^[1]. Shipments start today.

The TLP3475S is housed in an S-VSON4 package and features low on-state output resistance. The TLP3440S is housed in a new S-VSON4T package, which has the same industry-leading small footprint as the S-VSON4 but is thinner. The TLP3440S features low off-state output resistance.

The footprint of the new photorelays is 22.5% smaller than that of existing VSON4 packages^[2]. Used in combination, they will help to reduce the sizes of circuit boards for tester PEs^[3]. They can be also be used in gigahertz high speed signal transmission lines. Unlike typical photorelays, which have a maximum operating temperature of 85°C, the TLP3440S and TLP3475S can operate at up to 110°C, and therefore simplify system design.

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)

TDSC 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.
