MOC 3021

 It is a 6pin Random Phase optoisolators TRIAC  driver output

TRIAC
 
 


from Triode for Alternating Current, is a genericized tradename for an electronic component that can conduct current in either direction when it is triggered (turned on), and is formally called a bidirectional triode thyristor or bilateral triode thyristor.


Applications:
  • Solenoid/Valve Controls
  • Static ac Power Switch
  • Lamp Ballasts
  • Solid State Relays
  • Interfacing Microprocessors to 115 Vac Peripherals
  • Incandescent Lamp Dimmer
  • Motor Controls
