Product Description
Original bidirectional DIAC Trigger Diode DB3
Features
Vbo: 32 V and 40 V.
Low breakover current
Breakover voltage symmetry: 3V
Ecopack.®2 compliant
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 lights
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
Automatic manufacturing.
