DIAC | Explain In Hindi | Power Electronics

DIAC

  1. DIode for Alternating Current
  2. DIAC is a diode that conducts electrical current only after its breakover voltage (VBO) has been reached.
  3. A DIAC is a device which has two electrodes, four layers and it is a member of the thyristor family.
  4. The advantage of a DIAC is that it can be turned on or off simply by reducing the voltage level below its avalanche breakdown voltage.
  5. DIACs are bidirectional devices, their terminals are not labeled as anode and cathode but as A1 and A2 or main terminal MT1 and MT2. 
  6. DIACs are also called "symmetrical trigger diodes" due to the symmetry of their characteristic curve.
