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. Document Number 83627 Rev. 1.4, 26-Apr-04 A 1 6 MT2 C 2 5 NC NC 3 ZCC* 4 MT1 *Zero Crossing Circuit i179030 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/µs. The use of a proprietary dV/dt clamp results in a static dV/ dt of greater than 10 kV/µs. 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 Pchannel 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 offline 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. www.vishay.com 1 IL410/ IL4108 Vishay Semiconductors Order Information Part Remarks IL410 600 V VDRM, DIP-6 IL4108 800 V VDRM, DIP-6 IL410-X006 600 V VDRM, DIP-6 400 mil (option 6) IL410-X007 600 V VDRM, SMD-6 (option 7) IL410-X009 600 V VDRM, SMD-6 (option 9) IL4108-X006 800 V VDRM, DIP-6 400 mil (option 6) IL4108-X007 800 V VDRM, SMD-6 (option 7) IL4108-X009 800 V VDRM, SMD-6 (option 9) For additional information on the available options refer to Option Information.

When inductive loads with power factors less than 0.8 are being driven, include a RC snubber or a single capacitor directly across the device to damp the peak commutating dV/dt spike. Normally a commutating dV/dt causes a turning-off device to stay on due to the stored energy remaining in the turning-off device. But in the case of a zero voltage crossing optotriac, the commutating dV/dt spikes can inhibit one half of the TRIAC from turning on. If the spike potential exceeds the inhibit voltage of the zero cross detection circuit, half of the TRIAC will be held-off and not turnon. This hold-off condition can be eliminated by using a snubber or capacitor placed directly across the optotriac as shown in Figure 1. Note that the value of the capacitor increases as a function of the load current. .1 Ta = 25°C, PF = 0.3 .01 IF = 2.0 mA .001 0 iil410_01 50 100 150 200 250 300 350 400 IL - Load Current - mA(RMS) Figure 1. Shunt Capacitance vs. Load Current Document Number 83627 Rev. 1.4, 26-Apr-04 IL410/ IL4108 Vishay Semiconductors The hold-off condition also can be eliminated by providing a higher level of LED drive current. The higher LED drive provides a larger photocurrent which causes the phototransistor to turn-on before the commutating spike has activated the zero cross network. Figure 2 shows the relationship of the LED drive 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.

Typical Static Inhibit Voltage Limit Figure 13. 1- Apply a Capacitor to the Supply Pins at the Load-Side Technical Information Commutating Behavior The use of a triac at the output creates difficulties in commutation due to both the built-in coupled thyristor systems. The triac can remain conducting by parasitic triggering after turning off the control current. However, if the IL410/4108 is equipped with two separate thyristor chips featuring high dv/dt strength, no RC circuit is needed in case of commutation. 33 Ω 1 6 2 5 3 4 22 nF 220 V~ Current commutation: The values 100 A/ms with following peak reverse recovery current > 80 mA should not be exceeded. Avoiding high-frequency turn-off current oscillations: This effect can occur when switching a circuit. Current oscillations which appear essentially with inductive loads of a higher winding capacity result in current commutation and can generate a relatively high peak reverse recovery current. The following alternating protective measures are recommended for the individual operating states: iil410_14 Figure 14. 2 - Connect a Series Resistor to the Output and Bridge Both by a Capacitor 500 µH 1 6 2 5 3 4 22 nF 220 V~ iil410_15 Figure 15. 3 - Connect a Choke of Low Winding Cap. in Series, e.g., a Ringcore Choke, with Higher Load Currents Note: Measures 2 to 3 are especially required for the load separated from the IL410/ IL4108 during operation. The above mentioned effects do not occur with IL410/ IL4108 circuits which are Document Number 83627 Rev. 1.4, 26-Apr-04 www.vishay.com 7 IL410/ IL4108 Vishay Semiconductors connected to the line by transformers and which are not mechanically interrupted. In such cases as well as in applications with a resistive load the corresponding protective circuits can be neglected. Application Note • Over voltage protection: A voltage-limiting varistor (e.g. SIO VS05K250) which directly connected to the IL410/ IL4108 can protect the component against overvoltage. Control And Turn-On Behavior The trigger current of the IL410/ IL4108 has a positive temperature gradient. The time which expires from applying the control current to the turn-on of the load current is defined as the trigger delay time (tgd). On the whole this is a function of the overdrive meaning the ratio of the applied control current versus the trigger current (IF/IFT). If the value of the control current corresponds to that of the individual trigger current of IL410/4108 turn-on delay times amounts to a few milliseconds only. The shortest times of 5.0 to 10 µs can be achieved for an overdrive greater or equal than 10. The trigger delay time rises with an increase in temperature. For very short control current pulses (tplF < 500 µs) a correspondingly higher control current must be used. Only the IL410/ IL4108 without zero voltage switch is suitable for this operating mode. Zero Voltage Switch The IL410/ IL4108 with zero voltage switch can only be triggered during the zero crossing the sine AC voltage. This prevents current spikes, e.g. when turningon cold lamps or capacitive loads. Applications Direct switching operation: The IL410/ IL4108 switch is mainly suited to control synchronous motors, valves, relays and solenoids in Grätz circuits. Due to the low latching current (500 µA) and the lack of an RC circuit at the output, very low load currents can easily be switched. Indirect switching operation: The IL410/ IL4108 switch acts here as a driver and thus enables the driving of thyristors and triacs of higher performance by microprocessors. The driving current pulse should not exceed the maximum permissible surge current of the IL410/ IL4108. For this reason, the IL410/ IL4108 without zero voltage switch often requires current limiting by a series resistor. The favorably low latching current in this operating mode results in AC current switches which can handle load currents from some milliamperes up to high currents. www.vishay.com 8 Document Number 83627 Rev. 1.4, 26-Apr-04 IL410/ IL4108 Vishay Semiconductors Package Dimensions in Inches (mm) 3 2 1 4 5 6 pin one ID .248 (6.30) .256 (6.50) ISO Method A .335 (8.50) .343 (8.70) .039 (1.00) Min. .300 (7.62) typ. .048 (1.22) .052 (1.32) .130 (3.30) .150 (3.81) 4° typ . 18° .033 (0.84) typ. .018 (0.46) .020 (0.51) 3°–9° .033 (0.84) typ. .100 (2.54) typ i178014 Option 6 Option 7 .407 (10.36) .391 (9.96) .307 (7.8) .291 (7.4) .300 (7.62) TYP. .008 (.20) .012 (.30) .130 (3.30) .150 (3.81) .300–.347 (7.62–8.81) Option 9 .375 (9.53) .395 (10.03) .300 (7.62) ref. .028 (0.7) MIN. .180 (4.6) .160 (4.1) .0040 (.102) .0098 (.249) .315 (8.0) MIN. .014 (0.35) .010 (0.25) .400 (10.16) .430 (10.92) Document Number 83627 Rev. 1.4, 26-Apr-04 .331 (8.4) MIN. .406 (10.3) MAX. .012 (.30) typ. .020 (.51) .040 (1.02) .315 (8.00) min. 15° max. 18450 www.vishay.com 9 IL410/ IL4108 Vishay Semiconductors Ozone Depleting Substances Policy Statement It is the policy of Vishay Semiconductor GmbH to 1.
