The IL4116, IL4117, and IL4118 consists of an AlGaAs IRLED optically coupled to a photosensitive zero crossing TRIAC network. The TRIAC consists of two inverse parallel connected monolithic SCRs. These three semiconductors devices are assembled in a six pin 300 mil dual in-line package. High input sensitivity is achieved by using an emitter follower phototransistor and a cascaded SCR predriver resulting in an LED trigger current of less than 1.3 mA (DC). The IL4116, IL4117, IL4118 uses zero cross line voltage detection circuit witch consists of two enhancement MOSFETs and a photodiode. The inhibit voltage of the network is determined by the enhancement voltage of the n-channel FET. The P-channel FET is enabled by a photocurrent source that permits the FET to conduct the main voltage to gate on the n-channel FET. Once the main voltage can enable the n-channel, it clamps the base of the phototransistor, disabling the first stage SCR predriver. The blocking voltage of up to 800 V permits control of off-line voltages up to 240 VAC, with a safety factor of more than two, and is sufficient for as much as 380 VAC. Current handling capability is up to 300 mA RMS continuous at 25 °C. The IL4116, IL4117, IL4118 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. Applications include solid-state relays, industrial controls, office equipment, and consumer appliances.
