New high-current photorelays for factory automation

Toshiba Electronics Europe has five new high-current photorelays in DIP4 and DIP6 packages. These additions to its photorelay portfolio incorporate MOSFETs fabricated with the latest U-MOS VIII process. There five new photorelays (TLP3543A, TLP3545A, TLP3546A, TLP3556A and TLP3558A) offer multiple options, with an off-state output terminal voltage (VOFF) ranging from 30V to 200V and a steady on-state current (ION) from 0.7A to 5.0A – which is claimed to be the industry’s highest rating in a DIP6 package. Designed for efficient operation RON values are as low as 20mOhm for the 30V version. When not in operation, the current draw (IOFF) is max. 1µA. Designed primarily for rugged applications, the devices will be used for the replacement of mechanical relays in a wide range of factory automation and other industrial uses including building automation, industrial equipment, HVAC, ATE, semiconductor testing and security.
