The CTH217 Series is a general-purpose DC input optocoupler featuring a phototransistor optically coupled to a gallium arsenide infrared-emitting diode. Housed in a 4-lead half pitch Mini-Flat package, this series offers high isolation of 3750 VRMS and a wide operating temperature range of -55 C to 125 C. It is suitable for applications requiring high density mounting, such as DC-DC converters, programmable controllers, and telecommunication equipment. The series is compliant with RoHS, REACH, and Halogen regulations and holds multiple regulatory approvals including UL, VDE, CQC, and IEC standards.
