Photorelay targets industrial use with 40 to 100V control range

Toshiba Electronics Europe has added the TLP241B high-current photorelay to its optoelectronics portfolio. The 100V rated device comes in a compact DIP4 package and covers a wide control range. It is intended for use in industrial equipment, such as programmable logic controllers and I/O interfaces, as well as building automation systems such as heating, ventilation and air conditioning.

Toshiba says the TLP241B, which incorporates Toshiba’s U-MOS mosfets, is the first photorelay device to have an off-state output terminal voltage spanning from 40V to 100V which means it can replace larger scale electro-mechanical relays. A non-contact optical arrangement, rather than moving parts, helps to extend operational lifespan, reduce system complexity and provide a more rapid response.

The device has an on-state current rating of 2A (continuous) and 6A (pulsed). It also offers 5kV isolation capabilities, making them suitable for applications that require reinforced insulation, with an operating temperature range between -40 degrees C and 110 degrees C. Housed in a DIP4 package, gull wing options are available to aid surface mounting.

Toshiba Electronics Europe GmbH (TEE) is the European electronic components business of Toshiba Electronic Devices and Storage Corporation (Toshiba). TEE offers European consumers and businesses a variety of hard disk drive products plus semiconductor solutions for automotive, industrial, Internet of Things, motion control, telecoms, networking, consumer and white goods applications.

Along with hard disk drive products, the company provides power semiconductors and other discrete devices ranging from diodes to logic ICs, optical semiconductors, as well as microcontrollers and application specific standard products.
