5A Photorelays in DIP8 Packages

Toshiba Corporation's Storage & Electronic Devices Solutions Company today announced the addition of three new products to its line-up of photorelays that can replace mechanical relays in industrial applications, claiming an industry-leading 5A drive current for DIP8 package photorelays. Shipments of the new products, TLP3547, TLP3548 and TLP3549, start from today.

The TLP3547 is a 60V product claiming industry-leading 5A (maximum) drive current in an DIP8 package photorelay. The TLP3548 is a 400V product with 0.4A (maximum) drive current and high-speed switching of 1ms (maximum). The TLP3549 is the first photorelay to utilize a super-junction structure MOSFET and is a 600V product with 0.6A (maximum) drive current.

Unlike mechanical relays, photorelays have no physical contacts that are subject to wear and deterioration, an advantage that contribute to set reliability. Use of photorelays also supports development of smaller and thinner sets. In addition to this, Toshiba’s new photorelays guarantee a pulsed ON-state current that is three times larger than that of the continuous ON-state current, securing a margin for safety design.

Main applications are expected to include: replacement of mechanical relays, thermostats (HVAC), power supply control of network appliances (TCP/IP, IoT), factory automation equipment, ac servos, inverters, programmable logic controllers), power meters, smart meters, security related products, and automatic test equipment).
