DB3 DIAC Diode – Bidirectional Trigger Diode
1.50 EGP
The DB3 Diac is a semiconductor device commonly used as a triggering diode for TRIACs and thyristors in AC switching applications. It functions as a bidirectional trigger diode that allows current to flow only after the voltage exceeds a specific breakover threshold, making it ideal for phase control in light dimmers, motor speed controls, and other AC power control circuits.
