DB3 Datasheet | STMicroelectronics

DB3 DB4 SMDB3 ® DIAC Features s VBO : 32V and 40V s LOW BREAKOVER CURRENT DESCRIPTION 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 lamp ballasts. A new surface mount version is now available in SOT-23 package, providing reduced space and patibility with automatic pick and place equipment. DO-35 (DB3 and DB4) 2 3 SOT-23 (SMDB3)- Pin 1 and 3 must be shorted...
