Explore DIAC diodes for triggering TRIACs, phase-control circuits, dimmers and AC switching applications. Find bidirectional trigger diodes designed to provide reliable switching at a defined breakover voltage in electronic control and power circuits.
How to choose the right DIAC
Choose a DIAC according to its breakover voltage, breakover current, symmetry, power dissipation and package type. DIACs conduct in both directions after the applied voltage reaches the specified breakover level, making them commonly used for triggering TRIACs in AC phase-control circuits.
Before ordering, check the exact part number, breakover voltage range and package dimensions. For replacement applications, compare the electrical characteristics with the original component to ensure proper triggering behavior and compatibility with the surrounding circuit.
