High-current photorelays target factory automation
The new photorelays will be available in DIP4 and DIP6 packages and add to Toshiba’s portfolio of photorelays using MOSFETs fabricated with the latest U-MOS VIII process.
The five relays (TLP3543A, TLP3545A, TLP3546A, TLP3556A and TLP3558A) offer off-state output terminal voltages (VOFF) ranging from 30V to 200V and a steady on-state current (ION) from 0.7A to 5.0A – the industry’s highest rating in a DIP6 package. RON values are as low as 20mΩ for the 30V version. When not in operation, the current draw (IOFF) is a maximum of 1μA. The photorelays have a rated operating temperature of 110°C (max).
Replacing 1-Form-A mechanical relays with photorelays improves reliability and reduces space. 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.
