Toshiba launches high-current photorelays in DIP4 package

Products

Toshiba Electronics Europe launched two new high-current photorelays fabricated with its latest U-MOS IX semiconductor process.

The new TLP3553A and TLP3555A devices feature OFF-state output terminal voltage ratings of 30V and 60V, and on-state continuous current ratings of 4A and 3A – higher than previous generation products. When operated in pulsed mode, the current ratings increase to 9A for both devices.

Common applications for these devices include industrial equipment (PLCs, I/O interface, sensor controls), building automation systems (heating, ventilation and air conditioning, or HVAC), security equipment and the replacement of mechanical relays in legacy systems.

The TLP3553A features a low on-state resistance of just 50mΩ (max.), which is less than a typical mechanical relay (about 100mΩ).

The photorelays are rated for operation at temperatures between -40°C and +110°C, making it easy to achieve a thermal margin in designs.
