What will I learn?

The Diac and Triac Course gives you practical skills to design and refine reliable AC dimmer circuits. You learn device fundamentals, phase-angle control, waveform behavior, and harmonic impact, then move into EMI, thermal management, and safety standards. Through focused design steps, testing methods, and troubleshooting techniques, you gain confidence to create robust, production-ready dimmer solutions.

Elevify advantages

Develop skills

  • TRIAC/DIAC fundamentals: master structure, key ratings, and datasheet use fast.
  • Phase-angle dimming: design RC timing and firing angle for smooth lamp control.
  • EMI and thermal control: apply snubbers, filters, and heatsinking for robust TRIACs.
  • Safe mains design: follow creepage, grounding, and PPE rules for dimmer circuits.
  • Testing and debug: verify IGT, firing angle, and fix flicker, EMI, and misfiring.
