DB4 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 compact, SMD based designs for
automated manufacturing.
DB4 Features
VBO : 32 V and 40 V
Low breakover current
Breakover voltage symmetry : 3V
ECOPACK?2 compliant
DB4 Applications
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
