Description

MOC8080 Zero Crossing Optocoupler DIP – Triac Driver Opto-Isolator IC

The MOC8080 zero crossing optocoupler is a reliable opto-isolated triac driver IC designed for safe and efficient AC load switching. It integrates an infrared LED and a zero-crossing triac output, allowing switching to occur precisely at the AC zero-voltage point. This feature significantly reduces electromagnetic interference (EMI), inrush currents, and electrical noise. Packaged in a robust DIP-6 through-hole package, the MOC8080 is widely used in solid state relays, AC motor controllers, heating systems, and mains-isolated control circuits.

Applications

• AC solid state relays (SSR)
• Zero-noise AC load switching
• Heater and temperature control systems
• AC motor and fan control circuits
• Mains isolated microcontroller switching

How to Use

1. Connect a current-limiting resistor in series with the input LED.
2. Apply control signal from microcontroller or logic circuit.
3. Use external power triac for high-current AC loads.
4. Ensure load is AC only, not suitable for DC switching.
5. Maintain proper PCB clearance and safety isolation distances.
