DESCRIPTION
The IL4216, IL4217, and IL4218 product family consists of
an optically coupled GaAs IRLED to a photosensitive
thyristor system with integrated noise suppression circuit.
The thyristor system enables low trigger currents of 0.7 mA
and features a dV/dt ratio of greater than 10 kV/μs and load
voltages up to 800 V.
The IL4216, IL4217, and IL4218 product family is 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.

FEATURES
• Low trigger current IFT = 0.7 mA (typ.)
• ITRMS = 300 mA
• High static dV/dt ≥ 10 000 V/μs
