SMDB3

DB3, DB4, SMDB3 Datasheet Diac DO-35 2 3 1 SOT-23 Pin 1 and 3 must be shorted together 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 lamps 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.
