Description

The MOC3020 consists of an infrared LED optically coupled to a photodiode that drives a triac. When the LED is activated by an input signal, it emits infrared light, which is detected by the photodiode. This, in turn, triggers the triac driver, allowing the control of AC loads without any direct electrical connection between the control and load circuits.

Features

  • Zero-Crossing Triggering: Unlike the random-phase MOC3011, the MOC3020 offers zero-crossing detection, meaning it triggers the triac when the AC voltage waveform crosses zero. This reduces electromagnetic interference (EMI) and minimizes inrush currents.
  • High Isolation Voltage: Provides electrical isolation of up to 7500 Vrms between the input and output sides.
  • Low Input Current: The LED can be driven with relatively low input current, making it compatible with various control circuits.
  • Compact DIP Package: Available in a 6-pin Dual Inline Package (DIP), which is easy to integrate into designs.
  • High dv/dt Immunity: The IC is designed to handle high rates of voltage change without false triggering.

Specifications

  • Input Type: Infrared LED
  • Output Type: Photodiode driving a triac
  • Isolation Voltage: 7500 Vrms (minimum)
  • LED Trigger Current: 15mA (maximum)
  • Peak Repetitive Off-State Voltage (VDRM): 400V
  • On-State Current (IT): 100mA (maximum)
  • Critical Rate of Rise of Off-State Voltage (dv/dt): 10,000 V/μs
  • Zero-Crossing Voltage: ±20V
  • Package: 6-pin Dual Inline Package (DIP)

Applications

  • AC Power Switching: Ideal for switching AC loads such as lighting, motors, and heating elements in industrial and consumer electronics.
  • Solid-State Relays (SSRs): Used as a key component in solid-state relays, which offer faster and more reliable switching compared to mechanical relays.
  • Light Dimmer Circuits: Can be used in light dimming applications to control the brightness of incandescent bulbs.
  • Motor Speed Control: Employed in circuits designed to control the speed of AC motors.
  • Home Automation: Used in smart home devices to control various household appliances and lighting systems.
