THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 IL410, IL4108 Optocoupler, Phototriac Output, Zero Crossing, High dV/dt, Low Input Current Vishay Semiconductors Fig. 7 - Typical Trigger Delay Time Fig. 8 - Off-State Current in Inhibited State vs. IF/IFT 25 °C Fig. 9 - Power Dissipation 40 Hz to 60 Hz Line Operation Fig. 10 - Typical Static Inhibit Voltage Limit TRIGGER CURRENT VS. TEMPERATURE AND VOLTAGE The trigger current of the IL410, 4108 has a positive temperature gradient and also is dependent on the terminal voltage as shown as the fig. 11. Fig. 11 - Trigger Current vs. Temperature and Operating Voltage (50 Hz) For the operating voltage 250 VRMS over the temperature range - 40 °C to 85 °C, the IF should be at least 2.3 x of the IFT1 (2 mA, max.). Considering - 30 % degradation over time, the trigger current minimum is IF = 2 x 2.3 x 130 % = 6 mA iil410_09 tgd = f (IF/IFT 25 °C), VD = 200 V f = 40 to 60 Hz, Parameter: Tj 103 102 101 5 100 5 101 5 102 IF/IFT25 °C Tj = 25 °C 100 °C iil410_10 IDINH = f (IF/IFT 25 °C), VD = 600 V, Parameter: Tj 103 102 100 5 0 2 4 6 8 10 12 14 16 18 20 IF/IFT25 °C 101 5 Tj = 25 °C 100 °C 0.6 0.4 0.5 0.3 0.2 0.1 0 0 100 200 300 iil410_11 ITRMS (mA) 40 to 60 Hz Line operation, Ptot = f(ITRMS) 12 10 8 6 4 100 55 102 101 iil410_12 V IF/IFT25 °C VDINH min = f (IF/IFT25°C), parameter: Tj Device zero voltage switch can be triggered only in hatched are below Tj curves.
