Below is a complete technical paper analyzing the (often found in datasheets as DB2S, DB2M, or DB2G), which matches the "DB2" identifier and is typically available in the PDF format you requested. If you are actually looking for a Diac component (like the DB3), please see the note at the end.
Always verify the PDF’s digital signature or hash against values provided by Diac’s official channel.
The is a bidirectional trigger diode designed primarily for low-power phase-control AC switching circuits, such as lamp dimmers, universal motor speed controllers, and fluorescent light ballasts.
Many vendors hide older datasheets. Use the site search with exact phrase:
The Diac DB2 datasheet provides detailed information about the component's electrical characteristics, thermal characteristics, and mechanical characteristics. Here are some key points to look for: Diac Db2 Datasheet Pdf 14
The Diac Db2 Datasheet PDF 14 includes a diagnostic flowchart. Here is a summary.
This article serves three purposes:
from major manufacturers. Use DB3 datasheet as the functional replacement unless your component marking clearly indicates a different breakover voltage (check with a component tester or curve tracer).
The electrical parameters dictate how the DB2 functions under specific voltage and current loads. Breakover Voltage ( VBOcap V sub cap B cap O end-sub 28 V Typical: 32 V Maximum: 36 V Below is a complete technical paper analyzing the

Used to regulate the heating elements in appliances such as heaters and ovens.
The PDF typically includes:
), the "helpful feature" of the DB2 is its lower breakover voltage relative to its successors. Breakover Voltage ( cap V sub cap B cap O end-sub Typically falls around 28V to 36V The is a bidirectional trigger diode designed primarily
): The current that flows before the breakdown voltage is reached.
When using the DB2 in a circuit (like an AC motor speed control), ensure your RC network is tuned to hit the breakover voltage at the desired phase angle for smooth power variation.
