Toshiba Electronics Europe (“Toshiba”) has launched two new high current photorelays that are fabricated using the 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 [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). This ensures that operating losses are kept to a minimum when the device is used to replace mechanical relays such as 1-Form-A that are commonly used in industrial applications. The photorelays are rated for operation at temperatures between -40°C and +110°C, making it easy to achieve a thermal margin in designs.
When mechanical relays are replaced with photorelays, such as the TLP355xA devices, then system reliability is immediately improved. As the photorelays are physically smaller than a mechanical relay, and no additional driver is required, then space and weight is also saved. Both TLP3553A and TLP3555A are provided in a DIP4 package both with and without surface mount option.
Both devices are now shipping in production quantities
