Line-up of large-current products enhanced for replacement of mechanical relays in industrial applications
TOKYO — (BUSINESS WIRE) — July 19, 2016 — Toshiba Corporation’s (TOKYO: 6502) 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, including an industry-leading 5A large drive current for DIP8 package photorelays. Shipments of the new products, “TLP3547”, “TLP3548” and “TLP3549”, start from today.

Toshiba: DIP8 package 5A Drive Current Photorelay "TLP3547" (Photo: Business Wire)
“TLP3547” is a 60V product with an industry-leading 5A (max.) large drive current for a DIP8 package photorelay. “TLP3548” is a 400V product with 0.4A (max.) drive current and high-speed switching of 1ms (max.). “TLP3549” is the industry’s first photorelay to utilize a super-junction structure MOSFET, “DTMOS series”, and is a 600V product with 0.6A (max.) 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.
