DB3, DB4, SMDB3 DIAC Diodes
ST Microelectronics 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.
Features and Benefits
Applications
The DIAC, or 'diode for alternating current', is a diode that conducts current only after its breakover voltage has been reached momentarily.
