The is a bidirectional trigger diode designed specifically to operate in conjunction with Triacs and SCRs . It functions as a voltage-sensitive switch that remains non-conductive until a specific breakover voltage is reached, at which point it allows current to flow in either direction. Core Specifications of the DB2 DIAC
"Because," Elias said, heading for the exit, "Pages 1 through 13 would have told us to replace the whole compressor for fifty grand. Page 14 told us the Diac just needed a five-cent wire to stop being paranoid."
If your specific application requires a (a component used for triggering Triacs in light dimmers or motor speed controllers), you are likely looking for the DB3 or DB4 .
The series is designed specifically for high-efficiency, reliable triggering of TRIACs in AC power control circuits, offering a lower voltage threshold compared to its counterparts like the DB3. 2. The Diac DB2 Datasheet: 14 Critical Parameters Explained Diac Db2 Datasheet Pdf 14

It remains in a highly resistive, non-conducting state until the voltage across its two terminals reaches a specific threshold. Breakover Voltage ( VBOcap V sub cap B cap O end-sub
The is a bidirectional trigger diode designed primarily for phase control applications, such as lamp dimming and motor speed regulation. Often packaged in a hermetically sealed glass DO-35 case, it provides a stable and symmetrical trigger pulse for thyristors like TRIACs. Key Specifications and Features The is a bidirectional trigger diode designed specifically
Below is a technical post draft summarizing the DB2 specifications and its role in electronic design.
While the exact PDF is proprietary, authoritative sources (including Diac’s official website and IBM PartnerWorld documentation) consistently list the following sections. A genuine datasheet for version 14 will contain these technical details:
Here’s a curated list of for finding and understanding the DIAC (DB2) datasheet PDF — likely referring to the DIAC bidirectional trigger diode (DB3 / DB4 / DB6 type) often called “DB2” in some markings or generic equivalents. Page 14 told us the Diac just needed
