MOC3040 Phototriac Output Optocoupler (Pack Of 5)

Description

1. Optical Isolation: The MOC3040 provides electrical isolation between the input and output circuits. This isolation ensures the safety of low-voltage control electronics and protects them from high-voltage AC power circuits.
2. Input Side (LED): The input side of the MOC3040 consists of an infrared LED. When a forward current is applied to this LED, it emits infrared light. This light is used to trigger the output side.
3. Output Side (Phototriac): The output side of the MOC3040 is equipped with a phototriac, which is a light-triggered triac. A triac is a solid-state device used for switching AC loads. The phototriac can be triggered by the infrared light from the LED, allowing control of AC power.
4. Zero-Crossing Detection: The MOC3040 may include zero-crossing detection, enabling it to trigger the phototriac at specific points in the AC waveform, typically at the zero voltage crossing point. This feature minimizes EMI and ensures smooth switching of AC loads.
5. AC Input Compatibility: The MOC3040 is designed for use with AC input signals. It is commonly used in applications where you need to control AC power, such as in light dimmers, motor speed control, and heating control.
6. Compact DIP Package: The MOC3040 is often available in a Dual Inline Package (DIP) with through-hole pins for easy mounting on a circuit board.
