Devices also suitable for other industrial applications and can replace mechanical relays
Toshiba Electronics Europe has started to ship five new high-current photorelays in DIP4 and DIP6 packages. These additions to its portfolio of photorelays incorporate MOSFETs fabricated with the latest U-MOS VIII process.
There are a total of five new photorelays (TLP3543A, TLP3545A, TLP3546A, TLP3556A and TLP3558A). Together they offer multiple options, with an off-state output terminal voltage (VOFF) ranging from 30 V to 200 V and a steady on-state current (ION) from 0.7 A to 5.0 A – which is the industry’s highest rating in a DIP6 package. Designed for efficient operation RON values are as low as 20 mΩ for the 30 V version. When not in operation, the current draw (IOFF) is max. 1 μA.
The new photorelays 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/pulse on-state (IONP) current three times larger than the rated steady on-state current, contributing to design safety.
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 industrial equipment, building automation, HVAC, semiconductor testing, ATE and security.
