Toshiba TLP570x GaAℓAs Photocouplers integrate an aluminum gallium arsenide infrared Light-Emitting Diode (LED) optically coupled to an integrated high-gain, high-speed photodetector in a compact 6-pin SO6L package. The TLP570x series is physically smaller and thinner than a photocoupler in an 8-pin DIP package and complies with international safety standards for reinforced insulation. Toshiba TLP570x GaAlAs Photocouplers feature a smaller footprint solution for applications that require a safety standard certification. An internal noise shield delivers a guaranteed common-mode transient immunity of 20kV/μs.
Toshiba High-Speed Photocouplers consist of a high-output GaAℓAs light-emitting diode coupled with integrated high gain, high-speed photodetectors. Toshiba offers photocouplers compliant with various communication standards ranging from RS232 to those for factory networks. Many of these devices can operate from both 3.3V and 5V power supplies. Since these photocouplers can be used in mixed 3.3V/5V systems, common parts can be used across different product lines. Toshiba also offers an extensive lineup of photocouplers with an LED current as low as 1mA by leveraging the characteristics of high-power LEDs. These photocouplers can be directly driven by a microcontroller without an intervening buffer and help reduce system power consumption.
