• High CMR 15KV/us at VCM=1500V (ELM453)
• Guaranteed performance from 0°C to 70°C
• Wide operating temperature range of -40°C to 85°C
• Pb free and RoHS and Halogen free compliant
• cUL approved (No. E214129
• VDE approved (No. 40028116)
• SEMKO approved
• NEMKO approved
• DEMKO approved
• FIMKO approved
Description
The ELM452 and ELM453 devices each consist of an infrared emitting diode, optically coupled to a high speed photo detector transistor. A separate connection for the photodiode bias and output-transistor collector increase the speed by several orders of magnitude over conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor. The devices are packaged in industry standard 5pin SOP packages and are suitable for surface mounting.
Applications
• Line receivers
• Field bus communication and control.
• Power transistor isolation in motor drives
• Replacement for low speed phototransistor photo couplers
• High speed logic ground isolation
• Analog signal ground isolation
