Vishay IL205AT/206AT/207AT/208AT Optocoupler Datasheet
The IL205AT, IL206AT, IL207AT and IL208AT are optically coupled pairs featuring a GaAs infrared LED and a silicon NPN phototransistor in a SOIC‑8A package. The series offers high isolation (BVCEO 70 V, isolation test voltage 3000 VRMS) and a range of current transfer ratios (CTR) suited for high‑density surface‑mount applications.
The document provides absolute maximum ratings, electrical characteristics, typical switching behavior, package dimensions and compliance information such as RoHS and ozone‑depleting‑substance policies. It also includes legal disclaimer statements regarding product use and liability.
