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



Photocoupler for high speed communication

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.
