STMicroelectronics DIAC 45 V 2 A, DO-35, počet kolíků: 2 kolíkový

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.
