Description

The MOC3061 is an optoisolator with a built-in Triac driver. It provides optical isolation between its input and output, ensuring safe and reliable operation in circuits that require separation between the control logic and the AC load. The Zero-Crossing feature ensures that the Triac is triggered only when the AC waveform crosses zero voltage, reducing electromagnetic interference (EMI) and minimizing surge currents.

Features

  • Zero-Crossing Detection: The MOC3061 triggers the Triac only at the zero-crossing point of the AC waveform, ensuring a smooth turn-on and minimizing electrical noise and stress on the power components.
  • High Isolation Voltage: The device offers a high isolation voltage (typically 5,000 VRMS) between the input and output, providing safety in high-voltage applications.
  • Low Input Current: The input LED requires a relatively low drive current (10-15 mA typical) to activate the Triac.
  • dv/dt Protection: The device can withstand high dv/dt (rate of change of voltage) without false triggering, making it suitable for environments with electrical noise.
  • Compact Package: Available in a small 6-pin DIP or SMD package, allowing for easy integration into various circuit designs.
  • RoHS Compliant: The device is compliant with lead-free and RoHS standards.

Specifications

  • Input LED Forward Voltage (Vf): 1.2V (typical)
  • Input LED Forward Current (If): 10-15 mA (typical for operation)
  • Isolation Voltage: 5,000 VRMS (min)
  • Output Peak Blocking Voltage: 400V (min)
  • Trigger Current (Igt): 5 mA (max)
  • Static dv/dt: 1.5 kV/μs (min)
  • Zero-Cross Voltage: ±20V
  • Turn-On Time: 100 μs (max)
  • Holding Current (Ih): 5 mA (typical)
  • Operating Temperature Range: -40°C to +85°C
  • Package: 6-pin DIP or SMD

Applications

  • AC Load Switching: Ideal for controlling AC loads such as lighting, heaters, and motor speed controls.
  • Solid-State Relays: Used in solid-state relay designs for controlling high-power AC loads.
  • Industrial Automation: Suitable for use in industrial control systems where electrical isolation and safe switching are critical.
  • Home Appliances: Commonly used in the control of household appliances like washing machines, dishwashers, and HVAC systems.
