STMicroelectronics DIAC 36 V 1 A 3-Pin SOT-23

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
