The CT785 Series is a DC 4-Pin DIP Phototransistor Optocoupler, featuring a phototransistor optically coupled to a gallium arsenide infrared-emitting diode. It offers high isolation of 5300 VRMS and operates within a wide temperature range of -55 C to 125 C. Designed for applications such as switch mode power supplies, computer peripheral interfaces, and microprocessor system interfaces, this series is compliant with RoHS, REACH, and Halogen-free standards. Regulatory approvals from UL, VDE, CQC, and IEC are pending.
