Description

The Electronic Component Model 207A is an optically coupled pair with a Gallium Arsenide infrared LED and a silicon NPN phototransistor. It is designed to transmit signal information, including a DC level, while maintaining a high degree of electrical isolation between input and output. The component comes in a standard SOIC-8 small outline package for surface mounting, making it suitable for high density applications with limited space. It eliminates the need for through-holes and conforms to standards for surface mounted devices. With a specified minimum and maximum Current Transfer Ratio (CTR) and a high BVCEO of 70 volts, it provides a narrow tolerance in electrical design and a higher safety margin compared to the industry standard.
