Additional Details

The ISP620-1SM typically consists of an infrared emitting diode (IRED) and a phototransistor, optically coupled within a single package. When current flows through the IRED, it emits infrared light, which activates the phototransistor, allowing current to flow in the output circuit. The electrical isolation is achieved because there is no direct electrical connection between the input and output circuits. The device is available in surface mount packages. The CTR is a critical parameter that defines the ratio of output current to input current. Higher CTR values indicate more efficient signal transfer. The ISP620-1SM is designed to meet stringent safety standards and is commonly used in applications requiring reinforced insulation.
