If you have searched for the term , you are likely looking for one of three things: : The voltage reaches the specific DB2 threshold

When used to trigger a triac, the DIAC ensures symmetrical switching and reduces harmonics. The DB2’s 30 V VBO is well matched to the gate characteristics of common triacs like the BT136, BT139, or MAC series. The DB2’s 30 V VBO is well matched

In light dimmers, the DB2 discharges a capacitor into the gate of a TRIAC to start conduction.

This article provides a deep dive into the features, its functional characteristics, and top circuit applications. What is a DB2 DIAC?

A DIAC is a two-terminal semiconductor device that acts as a switch, remaining non-conductive until a specific breakover voltage cap V sub cap B cap O end-sub
