Non Compliant

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

For these non-cancellable (NC), and non-returnable (NR) products, Terms and Conditions apply.

The DIAC, or 'diode for alternating current', is a diode that conducts current only after its breakover voltage has been reached momentarily.
