The LTV817S-TA1-D-V is a surface-mount photocoupler from Lite-On Inc., designed for electrical isolation. It incorporates an infrared LED and a phototransistor. The 'S' indicates a surface-mount package, 'TA1' designates tape and reel packaging for automated assembly, 'D' specifies a particular CTR (Current Transfer Ratio) range, and 'V' may indicate a variant or refinement in specifications.

Applications:

• Surface Mount PCB Assembly: Designed for automated surface mount assembly lines.
• Industrial Control Systems: Provides isolation in industrial control equipment.
• Power Supplies: Used for feedback isolation in power supplies.
• Motor Control Circuits: Isolates control signals in motor control applications.
• Instrumentation: Used for isolation in sensitive instrumentation equipment.

Features:

• Surface Mount Package (S): Enables high-density circuit board designs.
• Tape and Reel (TA1): Suitable for automated pick-and-place assembly.
• CTR (Current Transfer Ratio): The 'D' designates a specific CTR range; datasheet must be consulted for specific values.
• High Isolation Voltage: Provides a high level of electrical isolation.
• Small Footprint: Saves valuable board space.

Benefits:

• Automated Assembly: Facilitates efficient and cost-effective manufacturing.
• Compact Size: Allows for smaller and more efficient circuit board layouts.
• Electrical Protection: Protects circuits from voltage spikes and surges.
• Enhanced Reliability: Improves system reliability by isolating sensitive components.
• Simplified Design: Makes the implementation of isolation easier.

Additional Details:

The LTV817S-TA1-D-V typically operates with a forward current of 50mA for the input diode and has a collector-emitter voltage rating of 80V. The operating temperature range is generally between -30°C and +100°C. The 'TA1' indicates tape and reel packaging for automated assembly. The 'D' signifies a particular CTR range; therefore, consulting the datasheet is crucial to determine the appropriate CTR value for the application. The isolation voltage is usually very high, often in the kilovolt range. The component is typically RoHS compliant.
