Product Details
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.
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
For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.
The DIAC, or 'diode for alternating current', is a diode that conducts current only after its breakover voltage has been reached momentarily.
