SMDB3 Triacs by STMicroelectronics

DIAC


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.
