VISHAY IL4208-X007

The IL420 and IL4208 consists of an optically coupled GaAs IRLED to a photosensitive thyristor system with integrated noise suppression and non-zero crossing functionality. The thyristor system enables low trigger currents of 1 mA and features a dV/dt ratio of greater than 10 kV/μs and load voltages up to 800 V. The IL420 and IL4208 are a perfect microcontroller friendly solution to isolate low-voltage logic from high voltage 120 VAC, 240 VAC, and 380 VAC lines and to control resistive, inductive, or capacitive AC loads like motors, solenoids, high power thyristors, or TRIACs and solid-state relays.
