High-current photorelay optimised for industrial implementation

Toshiba Electronics Europe has announced a new addition to its comprehensive optoelectronics portfolio. The TLP241B is a high-current photorelay, aimed at industrial equipment, including PLCs and I/O interfaces, and building automation systems like HVAC.

By including one of the company's ultra-advanced U-MOS MOSFETs, the device sets new performance benchmarks. It is the first photorelay device on the market to offer an off-state output terminal voltage spanning from 40V to 100V. The device offers the capacity to substitute larger scale electro-mechanical relays, offering a more reliable, cost-effective and space-saving option. By relying on a non-contact optical arrangement instead of moving parts, engineers may benefit from greater operational lifespan, decreased system complexity and speedy responsiveness.

Also, the device holds other key attributes that boosts its appeal. The device provides an on-state current rating of 2A (continuous) and 6A (pulsed). It also provides 5kV isolation capabilities, with an operating temperature range between -40C and 110C. This new photorelay is contained in a DIP4 package. Gullwing options are offered to aid surface mounting.
