IL410, IL4108 Vishay Semiconductors Optocoupler, Phototriac Output, Zero Crossing, High dV/dt, Low Input Current A 1 6 MT2 C 2 5 NC FEATURES • High input sensitivity NC 3 ZCC* • IFT = 2 mA, PF = 1.0 4 MT1 • IFT = 5 mA, PF 1.0 *Zero crossing circuit i179030_4 21842-1 • 300 mA on-state current V D E DESCRIPTION • Zero voltage crossing detector The IL410 and 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 mA (DC). 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 V, 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 VAC, 240 VAC, and 380 VAC lines to control resistive, inductive, or capacitive loads including motors, solenoids, high current thyristors or TRIAC and relays. • 600 V, 800 V blocking voltage • High static dV/dt 10 kV/μs • Very low leakage < 10 A • Isolation test voltage 5300 VRMS • Small 6 pin DIP package • Compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC APPLICATIONS • Solid-state relays • Industrial controls • Office equipment • Consumer appliances AGENCY APPROVALS • UL1577, file no.

The RC network is called snubber circuit. Note that the value of the capacitor increases as a function of the load current as shown in fig. 13. Failed to keep on As a zero-crossing phototriac, the commutating dV/dt spikes can inhibit one half of the TRIAC from keeping on If the spike potential exceeds the inhibit voltage of the zero cross detection circuit, even if the LED drive current IF is on. This hold-off condition can be eliminated by using a snubber and also by providing a higher level of LED drive current. The higher LED drive provides a larger photocurrent which causes the triac to turn-on before the commutating spike has activated the zero cross detection circuit. Fig. 14 shows the relationship of the LED current for power factors of less than 1.0. The curve shows that if a device requires 1.5 mA for a resistive load, then 1.8 times (2.7 mA) that amount would be required to control an inductive load whose power factor is less than 0.3 without the snubber to dump the spike. 0.001 0 iil410_01 50 100 150 200 250 300 350 400 IL - Load Current (mARMS) Fig. 13 - Shunt Capacitance vs. Load Current 2.0 NIFth - Normalized LED Trigger Current If the commutating dV/dt is too high, more than its critical rate (dV/dtcrq), the triac may resume conduction even if the LED drive current IF is off and control is lost. www.vishay.com 6 1 Cs - Shunt Capacitance (µF) The voltage across the triac will rise rapidly at the time the current through the power handling triac falls below the holding current and the triac ceases to conduct. The rise rate of voltage at the current commutation is called commutating dV/dt. There would be two potential problems for ZC phototriac control if the commutating dV/dt is too high. One is lost control to turn off, another is failed to keep the triac on. 1.8 IFth Normalized to IFth at PF = 1.0 TA = 25 °C 1.6 1.4 1.2 1.0 0.8 0.0 iil410_02 0.2 0.4 0.6 0.8 1.0 1.2 PF - Power Factor Fig. 14 - Normalized LED Trigger Current vs. Power Factor For technical questions, contact: [email protected] Document Number: 83627 Rev. 2.0, 29-Mar-11 This document is subject to change without notice.

Fig. 15 shows a basic driving circuit. For resistive load the snubber circuit RS CS can be omitted due to the high static dV/dt characteristic. The IL410, IL4108 switch acts here as an isolated driver and thus enables the driving of power thyristors and power triacs by microprocessors. Fig. 16 shows a basic driving circuit of inductive load. The resister R1 limits the driving current pulse which should not exceed the maximum permissible surge current of the IL410, IL4108. The resister RG is needed only for very sensitive thyristors or triacs from being triggered by noise or the inhibit current.
