High-current photo relays replace mechanical relays in factory automation
Five high-current photo relays are available from Toshiba Electronics Europe in DIP4 and DIP6 packages.
The additions to Toshiba’s portfolio of photo relays incorporate MOSFETs fabricated with the latest U-MOS VIII process.
The TLP3543A, TLP3545A, TLP3546A, TLP3556A and TLP3558A photo relays offer offer multiple options, with an off-state output terminal voltage (VOFF) ranging from 30 to 200V. On-state current is a steady 0.7 to 5.0A, which is claimed to be the industry’s highest rating in a DIP6 package. For efficient operation RON values are as low as 20-microOhm for the 30V version. When not in operation, the current draw is a maximum of one microA.
The new photo relays 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 degree C (max), making it easier to accommodate temperature margins in system designs, says Toshiba.
The photo relays provide a rated transient/pulse on-state current three times larger than the rated steady on-state current, contributing to design safety.
Designed primarily for rugged applications, the devices will replace mechanical relays in a range of factory automation and other industrial uses including industrial equipment, building automation, HVAC, semiconductor testing, automatic test equipment (ATE) and security.
