Toshiba's photocouplers offer 5Mbps communication with very low power consumption

Toshiba Electronics Europe (TEE) has launched two new photocouplers for high speed communication (5 Mbps) applications. The TLP2310 and TLP2710 have a 54% reduced power consumption of 6,78mW, compared to 14,8mW of a conventional product, like the TLP2355. Both have been certified to UL1577 and EN60747-5-5 standards, making them ideally suited for applications requiring high insulation performance, such as AC drives, servo amplifiers, I/O interface boards, photovoltaic devices and factory automation equipment.

The TLP2310 and TLP2710 integrate a very reliable, high output power infrared LED that delivers excellent lifetime characteristics and reduces the threshold input current by about 38% compared to a conventional product. By mounting a light receiving IC that uses a Bi-CMOS process in the output side, each of the photocouplers has a low supply current of max. 0,3mA, which is about 90% lower compared with the conventional product. Additionally, by sustaining the threshold input current at 1mA (max), they support bufferless direct drive by a microcomputer, and help reduce power consumption and the cost of equipment systems.

Both photocouplers support an operating temperature of 125°C (max) and a power supply voltage range between 2.7V and 5.5V. This contributes to lowering the voltage of devices that use these products.

Housed in packages with a max. height of 2,3mm, the TLP2310 is available in a 5pin SO6 package, with a clearance and creepage distance of minimum 5mm and isolation voltage of min. 3.75kVrms. The TLP2710 is housed in a SO6L package, with a clearance and creepage distance of minimum 8mm and an isolation voltage of min. 5kVrms.
