Original MOC3062 Optocoupler DIP-6 Fairchild
The Fairchild MOC3062 is an optocoupler, specifically designed for switching AC loads, which consists of an LED and a zero-crossing phototriac. Packaged in a 6-pin DIP form factor, it’s commonly used for applications that require electrical isolation while controlling AC power. Here’s an overview of its features and typical uses:
1. Structure and Working Principle
- LED and Zero-Crossing Phototriac: The MOC3062 includes an LED on the input side and a zero-crossing phototriac on the output. When current is applied to the LED, it emits light that activates the phototriac, allowing AC current to flow on the output side. The zero-crossing functionality ensures that switching happens only when the AC waveform crosses zero voltage, minimizing electrical noise and reducing stress on the connected load.
- Electrical Isolation: The MOC3062 provides high electrical isolation (up to 7500V) between input and output, making it suitable for applications where a microcontroller or low-voltage circuit controls high-voltage AC circuits.
2. Key Specifications
- Zero-Crossing Triggering: The MOC3062’s zero-crossing detection is a critical feature for switching AC loads smoothly, as it reduces electrical noise and helps to prevent surges.
- Maximum Output Voltage: It can handle an output voltage of up to 600V, which allows it to work with standard AC mains voltages.
- Trigger LED Current: The LED typically requires 15 mA to activate, which is low enough for direct interfacing with microcontrollers or other low-power control systems.
3. Applications
- AC Load Switching: It’s commonly used for switching AC loads, such as motors, lights, and heaters, especially in applications where isolation and noise reduction are essential.
- Dimmer Circuits: MOC3062 can be used in light dimmer applications, where smooth transitions and low noise are required.
- Home Appliances: This optocoupler is often found in appliances that require high-voltage isolation and AC load control, such as washing machines, dishwashers, and other consumer electronics.
- Motor Control: With its ability to switch high-voltage AC loads at zero-crossing points, it’s suitable for controlling AC motors in industrial or home automation applications.
The MOC3062 is widely used due to its reliability, effective AC load control with zero-crossing detection, and high electrical isolation, making it a robust solution for safely interfacing low-power control systems with high-voltage AC devices.
