Toshiba introduces high-current photorelay

Toshiba Electronics Europe has announced a new addition to its expansive optoelectronics portfolio.

The TLP241B is a high-current Photorelay, targeted at use in industrial equipment, such as programmable logic controllers (PLCs) and I/O interfaces, as well as building automation systems like HVAC (heating, ventilation and air conditioning).

Not only does it ncorporate one of Toshiba’s ultra-advanced U-MOS MOSFETs, it's the first photorelay device on the market to have an off-state output terminal voltage spanning all the way from 40V to 100V.

As a consequence, it has the capacity to replace larger scale electro-mechanical relays, providing a more reliable, cost-effective and space-saving alternative. By relying on a non-contact optical arrangement rather than moving parts, engineers can benefit from longer operational lifespan, reduced system complexity and more rapid responsiveness.

In addition, the TLP241B possesses other key attributes. The device has an on-state current rating of 2A (continuous) and 6A (pulsed). It also offers 5kV isolation capabilities, with an operating temperature range between -40℃ and 110℃. This new photorelay is housed in a DIP4 package. Gull wing options are available to facilitate surface mounting.
