KTLP166J Series

4PIN MINI-FLAT ZERO-CROSS

TRIAC DRIVER PHOTOCOUPLER

 Description

The KTLP166J 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 115/240

VAC lines, such as solid-state relays, industrial

controls,

motors,

solenoids

and

consumer

appliances, etc.
