The EL3082S(TA) is a Triac Driver Optocoupler with Zero Crossing Detection, manufactured by Everlight Electronics Co., Ltd. It integrates an infrared emitting diode (IRED) and a bidirectional silicon switch, designed to drive power triacs. The "S" indicates surface mount package and the "TA" represents tape and reel packaging. The zero-crossing feature helps minimize electromagnetic interference (EMI).

Applications:

• Solid State Relays (SSRs): Used to create SSRs for switching AC loads, providing isolation and reducing EMI.
• Lighting Control: Employed in dimming circuits for incandescent and some types of LED lighting, minimizing inrush current.
• Industrial Controls: Used in industrial automation systems to control AC loads like motors, heaters, and solenoids.
• Home Appliances: Found in appliance control circuits for switching power to various components.
• Temperature Controllers: Used in temperature control systems for switching heating elements.

Features:

• Zero-Crossing Detection: Reduces EMI by switching the triac at or near the zero-crossing point of the AC waveform.
• High Isolation Voltage: Provides electrical isolation between the control circuit and the AC load.
• High Blocking Voltage: Can withstand high AC voltages without breakdown.
• Surface Mount Package: Allows for automated assembly and space-saving on PCBs.
• Safety Approvals: Typically UL, VDE, and/or CSA approved for safety compliance.

Benefits:

• Reduced EMI: Minimizes electromagnetic interference, improving system performance and reducing noise.
• Electrical Isolation: Provides a safe barrier between the control circuitry and the high-voltage AC load.
• Improved System Reliability: Protects sensitive control circuits from voltage transients and noise.
• Simplified Design: Makes designing AC control circuits easier and more reliable.
• Extended Load Life: Zero-crossing switching can extend the life of connected loads, particularly incandescent bulbs.

Technical Specifications (Typical):

• Peak Blocking Voltage: 800V
• Isolation Voltage: 5000 VRMS
• On-State Current: 100 mA
• Trigger Current (IFT): 5 mA
• Holding Current (IH): 400 μA
• Operating Temperature Range: -40°C to +100°C
