Feb 20, 2013– Tokyo, Japan  (Techreleased) – Toshiba Corporation today announced that it has launched a photo transistor coupler for factory automation devices and air-conditioners that guarantees high temperature operation (Ta = 110°C max.) and high collector voltage (VCEO) of 350V.

The new product, “TLP188”, guarantees minimum creepage and clearance distance of 5mm, and can be used at up to 707 Vpk of maximum permissible operating isolation voltage, as specified in the EN 60747-5-5 safety standard. With a guaranteed internal insulation thickness of 0.4mm, TLP188 fully conforms with the reinforced insulation category of various safety standards.

TLP188 can replace the current Toshiba product, “TLP628 (DIP4 package)”, and can contribute to saving board space through its use of the smaller, thinner SO6 package.
