The Vishay optocoupler consists of an optically coupled GaAs IRLED to a photosensitive thyristor system with integrated noise suppression and non-zero crossing functionality. The IL4208 are a perfect microcontroller friendly solution to isolate low-voltage logic from high voltage and to control resistive, inductive, or capacitive AC loads like motors, solenoids, high power thyristors, or TRIACs and solid-state relays.Load voltage up to 800 VLow trigger current
