The ICPL2631SM with Optocouplers SMD-8 RoHS is a surface mount compatible optocoupler module manufactured by Isocom. It consists of an LED light source optically coupled to a high speed, high gain phototransistor. The optocoupler module is RoHS compliant and is typically used for high speed signal and data transmission applications in industrial, automotive, telecommunications and medical electronics. Features include high common mode noise immunity (CMRR) of up to 1000 V/µs, wide operating temperature range from -40°C to +85°C, low on-resistance and high off-state current transfer ratio (CTR). This optocoupler module is suitable for applications such as circuit isolation, motor drive control, isolated power supplies, data transmission, safety and signal tripping relay applications.
