20kbps to 100kbps communication photocouplers from Toshiba lower costs, power consumption

USA: Toshiba America Electronic Components Inc., (TAEC) announced the launch of two new communication photocouplers – theTLP2301 (20kps) and TLP2303 (100kps).

Supporting RS-232 communication speed of 9.6kbps or 19.2kbps to RS-232C communication speed of 115.2kbps transmission rates for isolated communication interfaces in factory automation devices, air-conditioners, smart meters and more, these new optimal speed photocouplers bring excellent cost/performance ratios and can be driven at a low input current of 1 mA.

Isolated communication interfaces for factory automation devices (such as PLC and inverters), home appliances and housing equipment (such as air conditioners and smart meters) use a wide range of transmission rates to communicate. Until now, photocouplers with optimal speed transmission rates were not available. This forced users to choose either general-purpose transistor couplers, which provide insufficient performance, or 1 Mbps-class IC couplers, which provide the performance needed, but at a very high cost.

Toshiba developed the TLP2301 and TLP2303 to fill this gap in the market. The new photocouplers achieve a high current transfer ratio (IC/IF) and switching under low input current conditions – leading to reductions in power consumption and costs in the wide range of products that use photocouplers.
