description
These optocouplers consist of two gallium-arsenide light-emitting diodes connected in a reverse-parallel configuration for ac-input applications and a silicon n-p-n phototransistor per channel. The TIL920 has one channel in a 4-pin package, the TIL921 has two channels in an 8-pin package, and the TIL922 has four channels in a 16-pin package. The standard devices, TIL920, TIL921, and TIL922, are tested for a current-transfer ratio of 20% minimum. Devices selected for a current-transfer ratio of 50% and 100% minimum are designated with the suffix A and B respectively.

This rating applies for sine-wave operation at 50 or 60 Hz. Service capability is verified by testing in accordance with UL requirements. This value applies when the base-emitter diode is open circuited. Derate linearly to 100C free-air temperature at the rate of 0.67 mA/C. Derate linearly to 100C free-air temperature at the rate of 2 mW/C. Derate linearly to 100C free-air temperature at the rate of 2.67 mW/C.
