KTLP161G Series
cosmo
Description
The KTLP161G series consist of a GaAs
infrared emitting diode optically coupled to a
monolithic silicon detector performing the function of
a zero voltage crossing bilateral TRIAC driver. They
are designed for use with a TRIAC in the interface of
logic systems to equipment powered from 115 VAC
lines, such as solid-state relays, industrial controls,
motors, solenoids and consumer appliances, etc.
