STMicroelectronics Diac; 2A; DO35; 35÷45V; THT; Ammo Pack; DB4-ST [DB4]
DB3, DB4, SMDB3 DIAC Diodes ST Microelectronics 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 fluorescent lamp ballasts. The surface mount SOT23-3L package allows compact, SMD based designs for automated manufacturing. Features and Benefits VBO: 32 V and 40 V Low breakover current Breakover voltage symmetry: 3V ECOPACK®2 compliant Applications Triggering device for Triac or SCR based motor/ light dimmer 32 V trigger device for oscillator circuit Start-up triggering in lighting ballast for CFL, TL or LED lamps The DIAC, or 'diode for alternating current', is a diode that conducts current only after its breakover voltage has been reached momentarily.
