LTV-817-C

The LTV-817-C is a small, low-cost optocoupler consisting of an infrared emitting diode optically coupled to a phototransistor or photodarlington detector. It provides electrical isolation between input and output circuits while allowing the transfer of signals via optical transmission.

Key Features:

• Optical Coupling: The device uses light to transmit signals across an isolation barrier, providing electrical isolation between input and output circuits. This prevents noise, ground loops, and voltage differences from affecting sensitive components.

• Compact Design: The LTV-817-C is housed in a compact and space-saving package, making it suitable for applications with limited board space.

• Wide Operating Temperature Range: It operates reliably over a wide temperature range, making it suitable for use in various environmental conditions.

• High Isolation Voltage: The optocoupler provides high isolation voltage between input and output circuits, ensuring safety and reliability in high-voltage applications.

• High CTR (Current Transfer Ratio): It features a high current transfer ratio, indicating the efficiency of transferring current from the input to the output side.

• Low Input Power Consumption: The optocoupler consumes low input power, making it energy-efficient and suitable for battery-powered or low-power applications.

• RoHS Compliance: The LTV-817-C complies with the Restriction of Hazardous Substances (RoHS) directive, ensuring it meets environmental standards for the elimination of hazardous materials in electronic components.

Applications:

• Isolated Signal Transmission: Used to transmit signals across isolation barriers in applications such as power supplies, industrial controls, and instrumentation.
