The LTV-816-C-CU is a single-channel phototransistor optocoupler manufactured by Lite-On Inc. It is designed to provide electrical isolation between different circuits, protecting sensitive components from high voltages and preventing ground loops. The device utilizes an infrared emitting diode (IRED) and a phototransistor to achieve this isolation.

Applications

• Programmable Logic Controllers (PLCs)
• Industrial Control Equipment
• Microcontroller Isolation
• Power Supply Isolation
• Signal Transmission in Noisy Environments

Features

• High Isolation Voltage: Provides a high level of electrical isolation, typically several kilovolts.
• Compact Package: Allows for efficient use of board space.
• CTR (Current Transfer Ratio): The 'C' designation likely indicates a specific CTR range.
• RoHS Compliant: Meets environmental standards for the reduction of hazardous substances.
• Low Input Current: Requires minimal current to activate the input LED.

Benefits

• Enhanced Safety: Protects sensitive circuitry from high voltage transients and surges.
• Improved Signal Integrity: Eliminates ground loops and reduces noise in signal transmission.
• Simplified Design: Reduces the complexity of isolating different circuit sections.
• Increased Reliability: Protects against voltage spikes and other electrical disturbances.
• Cost-Effective Isolation: Provides a simple and economical method for electrical isolation.

Additional Details

The LTV-816-C-CU optocoupler functions by converting an electrical signal into light using an IRED. The light then activates a phototransistor on the output side, completing the circuit and transferring the signal. Because the input and output sides are optically coupled, there is no direct electrical connection, providing the desired isolation.

The 'CU' suffix may indicate specific packaging or testing characteristics. The 'C' in the part number relates to a specific Current Transfer Ratio (CTR) range, essential for ensuring consistent performance in various applications.
