(Pack of 5) DB3 DIAC Trigger Mode Diode The DB3 DIAC is a bidirectional trigger diode used primarily to provide a consistent and symmetrical breakdown characteristic in AC control circuits. It remains in a high-impedance, non-conducting state until the applied voltage reaches its breakdown threshold (typically around 30 V), at which point it switches to a low-impedance conducting state in either polarity.This behavior makes the DB3 ideal for triggering TRIACs and other AC switching devices at a predictable voltage point. The pack of 5 ensures you have multiple units for experiments, repairs, or production needs.Click here to view related productsFeaturesBidirectional triggering — conducts in both directions after breakdownBreakover voltage around ~30 V — consistent trigger pointHigh switching speed for reliable triggeringCompact diode package — easy to integrate on PCBsStable characteristics for repeatable performancePack of 5 units — great value for projects and sparesApplicationsTRIAC gate triggering in AC power control circuitsPhase control circuits for light dimmers and motor speed controllersSolid-state relaysAC control modules in home appliancesWaveform shaping and triggering networks*Product image for illustration purposes only, actual product may vary.
