DESCRIPTION
• CSA
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.
• DIN EN 60747-5-5 (VDE 0884-5), available with option 1
• FIMKO
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.
