SKU: DIAC DB3 Categories: ,

DB3, DB4, SMDB3 DIAC Diodes

ST Microelectronics Functioning as a trigger diode with a fixed voltage reference, the DB3/DB4 series can be used in conjunction with triacs for simplified gate control circuits or as a starting element in fluorescent lamp ballasts.

The surface mount SOT23-3L package allows compact, SMD based designs for automated manufacturing.

Features and Benefits

    • VBO: 32 V and 40 V
    • Low breakover current
    • Breakover voltage symmetry: 3V
  • ECOPACK®2 compliant


    • Triggering device for Triac or SCR based motor/ light dimmer
    • 32 V trigger device for oscillator circuit
  • Start-up triggering in lighting ballast for CFL, TL or LED lamps

The DIAC, or ‘diode for alternating current’, is a diode that conducts current only after its breakover voltage has been reached momentarily.
