Overview
The DB3TG is a DIAC (Diode for Alternating Current) produced by STMicroelectronics. It functions as a trigger diode with a fixed voltage reference and is designed to be used in conjunction with Triacs for simplified gate control circuits or as a starting element in fluorescent lamp ballasts. The device is packaged in a DO-35 format and is known for its tight breakover voltage (VBO) range of 30 to 34 volts.
