DESCRIPTION
The VOT8121A consists of a GaAs IRLED optically coupled
to a photosensitive TRIAC packaged in a board space
saving DIP-4 package.
The VOT8121A isolates low-voltage logic from 120 VAC,
240 VAC, and 380 VAC lines to control resistive, inductive, or
capacitive loads including motors, solenoids, high current
thyristors or TRIAC and relays.
