LLDB4

DIACs

DIACThyristor TriggerPhase Control

The LLDB4 is a bidirectional trigger diode (DIAC) used for phase control in AC circuits, featuring a 35V-45V breakover voltage range in a surface-mount MiniMELF package.

Best for

  • Lamp dimming circuits
  • Universal motor speed control
  • Heat control systems

Avoid if

  • Applications requiring precise trigger voltages outside the 35V-45V range

Check before use

  • Trigger voltage compatibility with the gate of the controlled thyristor
