The LTV-816-CD-LG is a single-channel phototransistor optocoupler produced by Lite-On Inc. This device provides electrical isolation between circuits, preventing high voltages and transients from damaging sensitive components. It accomplishes this by using an infrared emitting diode (IRED) to transmit a signal to a phototransistor across an isolation barrier.

Applications

• Industrial Control Systems
• Programmable Logic Controllers (PLCs)
• Power Supply Isolation
• Microcontroller Input/Output Isolation
• Data Transmission in Noisy Environments

Features

• High Isolation Voltage: Offers significant electrical isolation, protecting circuits from voltage spikes.
• Compact Package: Space-saving design for high-density applications.
• CTR (Current Transfer Ratio): The 'CD' likely designates a specific CTR range.
• RoHS Compliant: Adheres to environmental standards regarding hazardous substances.
• Low Input Current: Requires minimal current to activate the input diode.

Benefits

• Improved Safety: Protects against high voltage transients and electrical noise.
• Enhanced Signal Integrity: Prevents ground loops and reduces noise interference.
• Simplified Circuit Design: Eases the implementation of isolation in various applications.
• Increased System Reliability: Reduces the risk of damage from electrical disturbances.

Additional Details

The LTV-816-CD-LG consists of an IRED and a phototransistor separated by an insulating layer. When the IRED is energized, it emits infrared light that triggers the phototransistor, allowing current to flow. This optical coupling provides electrical isolation.

The 'LG' suffix may refer to specific packaging or testing parameters relevant to the application. The 'CD' portion indicates a defined Current Transfer Ratio range, ensuring that the device meets specific performance criteria.
