: Its primary role is to provide a reliable, symmetrical trigger pulse to fire a TRIAC in AC power control applications. This setup is used in household dimmer switches, fan speed regulators, electric heater controls, and universal motor speed controls for power tools. The DIAC ensures the TRIAC fires cleanly and evenly at the desired point in each AC half-cycle.

) and 2A peak pulse current, designed for phase control in AC applications like motor speeds and light dimmers. Frequently found in DO-35 packaging, these components operate by providing a precise trigger pulse in both halves of an AC cycle.
