DESCRIPTION

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.
