STMICROELECTRONICS DB3TG DIAC switch

The DB3TG is a 2-pin DIAC used as a trigger diode with a fixed voltage reference, ideal for gate control circuits with triacs or as a starting element in fluorescent lamp ballasts. Featuring a breakover voltage range of 30 to 34V, a typical output voltage of 5V, a rise time of 2 microseconds, and leakage current of 10 microamperes, it operates reliably in industrial environments. With a maximum repetitive peak on-state current of 2A and a storage temperature range from -40°C to +125°C, this component ensures dependable switching performance.
