Frequently Asked Questions

Q: What is the difference between MOC3063 and EL3063?

A: The MOC3063 and EL3063 are functionally equivalent, pin-compatible optoisolator TRIAC driver ICs produced by different manufacturers. They share the same DIP-6 footprint, zero-crossing detection circuit, and TRIAC driver output characteristics, making them interchangeable in most circuit designs.

Q: What does zero-cross detection mean in an optoisolator?

A: Zero-cross detection means the optoisolator only triggers the TRIAC output at the point where the AC waveform crosses zero volts. This greatly reduces switching transients, electrical noise, and EMI — making it ideal for noise-sensitive applications like lighting control or motor switching.

Q: Can I use the MOC3063 with an Arduino or other microcontroller?

A: Yes. The MOC3063 is commonly used with microcontrollers such as Arduino, ESP32, and PIC to switch high-voltage AC loads safely. A low-voltage DC signal from the microcontroller drives the LED input side, while the TRIAC output side controls the AC load — providing full galvanic isolation between your control circuit and mains voltage.
