The ILD205T, ILD206T, ILD207T, ILD211T, and ILD213T are dual-channel optocouplers featuring a gallium arsenide infrared LED and a silicon NPN phototransistor. They transmit signal information while maintaining high electrical isolation between input and output. These devices are supplied in a surface-mountable SOIC-8 package, ideal for high-density applications with limited space. The specified minimum and maximum CTR offers a narrow tolerance for adjacent circuit design, and the high BVCEO of 70 V provides an enhanced safety margin.
