SMDB3 Overview
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.
