IL410/IL4108 - Optocoupler, Phototriac Output, Low Input Current - Vishay Optocouplers

IL410 IL4108 - Optocoupler Phototriac Output, Low Input Current - Vishay Optocouplers IL410 DESCRIPTION The IL410 IL4108 consists of a GaAs IRLED optically coupled to a photosensitive zero crossing Triac network. The Triac consists of two inverse parallel connected monolithic SCRs These three semiconductors are assembled in a six pin 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 2.0 mA (DC). The IL410 IL4108 uses two Discrete SCRs resulting in a commutating dV/dt greater than 10 kV/ms. The use of a proprietary dV/dt clamp results in a static dV/dt of greater than 10 kV/ms. This clamp circuit has a MOSFET that is enhanced when high dV/dt spikes occur between MT1 and MT2 of the Triac When conducting, the FET clamps the base of the Phototransistor disabling the first stage SCR predriver. The zero cross line voltage detection circuit 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 600/800 V blocking voltage 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. The IL410 IL4108 isolates low-voltage Logic from 120, 240, and 380 VAC lines to control resistive, inductive, or capacitive loads including motors, solenoids, high current Thyristors or Triac and relays.
