The IL206AT is a 1-channel 8-pin Phototransistor Output Optocoupler with base connection. It is optically coupled pairs with a gallium arsenide infrared LED and a silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. It is ideally suited for high density application with limited space. In addition to eliminating through-hole requirements. A specified minimum and maximum CTR allows a narrow tolerance in the electrical design of the adjacent circuits. The high BVCEO of 70V gives a higher safety margin compared to the industry standard 30V.
