This is an GaAs Ired and the Photo IC which is extremely useful for the use in various optocoupler arrangements

The above picture shows a physical description of the TLP559.

TLP559 consists of a Ga-As high-output light-emitting diode and a high-speed detector of one chip photo-diode sensor.

TLP559 has no internal base connection and a faraday shield integrated on the photodetector chip provides an effective common mode noise transient immunity.
