) is reached. Once triggered, it conducts in either direction, allowing current to flow until it drops below a holding threshold. Its structure typically consists of three or five alternating P and N layers, effectively functioning like two antiparallel diodes without a control gate. Technical Specifications Based on standard DIAC Datasheets , the DB2 series typically features: Datasheet - DB3, DB4, SMDB3 - Diac - STMicroelectronics Once triggered, it conducts in either direction, allowing

The is a robust, cost-effective trigger device for any AC phase control circuit. By understanding its 14 top parameters —from breakover voltage (32V) to dv/dt immunity (50 V/µs)—you can design dimmers, regulators, and controllers that operate reliably for years.

: While traditionally available in the axial DO-35 glass package , modern DB2 variants are frequently found in SOT-23 surface-mount packages for high-density PCB designs.

This is the "ghost story" of the component. Once the DIAC breaks over at 32 volts, its internal resistance collapses. It actually lowers its voltage requirement to stay on. It enters a valley where it conducts easier than before. It is a one-way door; once you push the DIAC through that 32-volt wall, it tumbles down the other side, conducting freely until the current drops to almost nothing.
