Toshiba Electronics has introduced the TLP241B, a high current photorelay for industrial equipment such as programmable logic controllers and I/O interfaces. Integrated with the U-MOS process-based MOSFET, the TLP241B has an extended OFF-state output terminal voltage up to 100V. Housed in a DIP4 package, the TLP241A photorelay delivers 2A ON-state current and 5kV isolation voltage hence can be used in a variety of applications.


The absence of moving contacts makes it the best replacement for the 1-Form-A contact mechanical relay. With a fast response time, the device provides a low current drive for improving the product's life. In a PCB space-saving smaller package, the TLP241A can deliver a maximum operating temperature of 110°C.


This new photorelay can be used in industrial equipment such as programmable logic controllers in the I/O interface and various sensor controls. It can also be used as a replacement for mechanical relays and in Building automation systems such as heating, ventilation, air conditioning (HVAC), and thermostats.
