SMDB3 Datasheet - STMicroelectronics

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 compatibility with automatic pick and place equipment.

FEATURES
■ VBO : 32V and 40V
■ LOW BREAKOVER CURRENT
