KTLP3503 Series
8PIN ZERO-CROSS TRIAC DRIVER
PHOTOCOUPLER
 Description
The KTLP3503 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 and a main output
power TRIAC. 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.
