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
