Description

The MOC3063 is an optoisolator with an internal LED and a Triac driver. When a sufficient current is applied to the LED, it emits light that triggers the Triac driver, allowing current to flow through the load. The Zero-Crossing detection feature ensures that the Triac is triggered only when the AC waveform crosses zero voltage, which minimizes electrical noise and surge currents, leading to smoother operation.

Features

  • Zero-Crossing Triggering: The MOC3063 triggers the Triac only at the zero-crossing point of the AC waveform. This reduces the generation of electromagnetic interference (EMI) and inrush currents, improving overall circuit reliability.
  • High Isolation Voltage: It provides a high isolation voltage (typically 5,000 VRMS) between the input and output, ensuring safe operation in circuits where high voltages are present.
  • Low Input Current Requirement: The LED input requires a low drive current (10-15 mA typical), making it compatible with a wide range of control circuits.
  • High Static dv/dt Capability: The device can handle high dv/dt (rate of change of voltage) without unintended triggering, which is crucial for operation in noisy electrical environments.
  • Compact 6-Pin DIP or SMD Package: Available in a standard 6-pin DIP or surface-mount package, making it easy to integrate into various designs.
  • RoHS Compliant: The IC is environmentally friendly, meeting lead-free and RoHS compliance standards.

Specifications

  • Input LED Forward Voltage (Vf): 1.15V (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 various AC loads like lamps, heaters, and fans.
  • Solid-State Relays: Commonly used in solid-state relays to safely control high-power AC devices with low-power control signals.
  • Home Automation Systems: Utilized in systems that automate household appliances, offering safe control over lighting and other devices.
  • Industrial Control Systems: Suitable for industrial applications requiring reliable AC load control with electrical isolation.
  • Consumer Electronics: Used in devices where reliable and noise-free switching is crucial, such as in dimmers, motor controls, and HVAC systems.
