SMDB3 Description

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 pact, SMD based designs for automated manufacturing. DB3, DB4, SMDB3 Characteristics.

SMDB3 Key Features

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

SMDB3 Applications

  • Triggering device for Triac or SCR based motor / light dimmer
  • 32 V trigger device for oscillator circuit
