Description

DB3 DIAC FEATURES VBO : 32V and 40V LOW BREAKOVER CURRENT DO-35 DESCRIPTION (DB3 and DB4) 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 fluorenscent 2 lamp ballasts. 3 A new surface mount version is now available in 1 SOT-23 package, providing reduced space and compatibility with automatic pick and place SOT-23 equipment.
