Toshiba Launches 15Mbps Photocouplers Realizing Low Power Consumption

TOKYO — (BUSINESS WIRE) — July 25, 2013Toshiba Corporation (TOKYO: 6502) today announced that it has launched photocouplers, “TLP2361” and “TLP2161”, that combine 15Mbps high-speed communication with low power consumption. Mass production is scheduled to start in August, 2013.

The products incorporate Toshiba’s original infrared LED. The LED’s high output and reliability secure low input current operations and reduce threshold input current by approximately 54% compared with equivalent products1. This LED’s stable output under high ambient temperature guarantees operation up to 125 degrees Celsius, the industry’s highest class2 of operation. Fabricated with Bi-CMOS process, supply current per channel is lowered to 1mA (max.), which cuts total supply current by approximately 66% for “TLP2361”, and approximately 60% for “TLP2161”.

“TLP2361”, with a small SO6 package, achieves clearances and creepage distance of 5mm (min.) and complies with the reinforced insulation3 class of overseas safety standard (EN60747-5-5). “TLP2161”, incorporating two circuits in SO8 package, reduces mounting area by approximately 40%, compared with two units of “TLP2361”, and contributes to downsizing of applications and reduction of PCB cost.
