The LTV-817SC-TA1 is a surface mount photocoupler manufactured by Lite-On Inc., providing electrical isolation between circuits. It consists of an infrared LED and a phototransistor. The 'S' indicates a surface mount package, 'C' designates a specific CTR (Current Transfer Ratio) range, and 'TA1' likely refers to a particular tape and reel packaging configuration for automated assembly.

Applications:

• SMT PCB Assembly: Optimized for surface mount technology assembly processes.
• Industrial Control Equipment: Used for isolating control signals in industrial machinery.
• Power Supplies: Provides feedback isolation in switching power supplies.
• Motor Control Circuits: Isolates control signals for motor drives.
• Communication Interfaces: Provides isolation in data communication systems.

Features:

• Surface Mount Package (S): Enables high-density PCB designs.
• CTR (Current Transfer Ratio): The 'C' designates a specific CTR range, which must be verified via the datasheet.
• Tape and Reel (TA1): Supplied on tape and reel for automated pick-and-place assembly.
• High Isolation Voltage: Provides high voltage electrical isolation.
• Compact Size: Saves valuable board space.

Benefits:

• Efficient Assembly: Streamlines SMT assembly processes, reducing manufacturing costs.
• Space Savings: Allows for more compact and efficient circuit board layouts.
• Electrical Safety: Protects circuits from high-voltage surges and transients.
• Improved Reliability: Enhances system reliability through electrical isolation.
• Simplified Design: Simplifies the implementation of isolation in circuit designs.

Additional Details:

The LTV-817SC-TA1 typically features a forward current rating of 50mA for the input diode and a collector-emitter voltage rating of 80V. The operating temperature range is usually between -30°C and +100°C. The 'TA1' designates that the component is provided on tape and reel, essential for automated assembly lines. The 'C' identifies a particular CTR range, which is a critical parameter for circuit design, and must be confirmed with the datasheet. The isolation voltage rating is typically very high, providing excellent protection against high-voltage conditions. The component is typically RoHS compliant.
