Toshiba Debuts New High-Speed Photocoupler

January 20, 2016

Delivers Creepage and Clearance Distance of 8mm

Toshiba TLP2768A

IRVINE, Calif., -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the launch of a new high-speed photocoupler that offers protection against extreme operating temperatures. The TLP2768A is capable of sustaining data rates up to 20 Mbps1, making it suitable for use in high-speed communication interfaces in factory automation systems, measurement and control equipment and plasma display panels. 

The TLP2768A features an operating temperature range of -40 to 125°C, enabling it to be used in increasingly compact industrial equipment that contains a greater density of components and therefore has higher internal temperatures. An open-collector output allows for both sink and source drive implementations. The TLP2768A supports both 3.3 and 5.5V power supplies, making it compatible with a wide range of existing industrial applications as well as ensuring it meets the needs of new and emerging low-voltage designs.

Toshiba’s TLP2768A high-speed photocoupler consists of a high-output GaAℓAs light-emitting diode coupled with integrated high gain, high-speed photodetectors. It features an inverter-logic output and operates over an extended temperature range while complying with the reinforced isolation class requirements of international safety standards. Housed in Toshiba’s ultra-thin S06L package, the TLP2768A offers a maximum height of just 2.3mm, which means a thickness reduction of approximately 45 percent2, yet achieves a very high minimum isolation voltage rating of 5000Vrms. The S06L package is able to maintain creepage and clearance distances up to 8mm.
