DB3

BIDIRECTIONAL TRIGGER DIODE

●

●

Features

Breakover voltage range : 28 to 36V

Applications

Functioning as a trigger diode with a fixed voltage

reference, the DB3 can be used in conjunction

with triacs for simplified gate control circuits or as

a starting element in fluorescent lamp ballasts.
