The following specifications are typical for the DB2/DB3 series DIACs: Breakover Voltage ( VBOcap V sub cap B cap O end-sub

The DB2 series is closely related to industry-standard models like the DB3 and DB4. It features a glass-passivated structure that offers high reliability and thermal stability. Below are the key engineering metrics typical of this series: Breakover Voltage ( VBOcap V sub cap B cap O end-sub

The is almost always paired with a TRIAC (e.g., BT136, BT139) to form a phase-control circuit. Here is a simplified sequence: diac db2 datasheet pdf 14 top

A key advantage of the DIAC is its symmetrical switching. The breakdown voltages for the positive and negative half-cycles of AC are nearly identical, with a tolerance typically within for the DB series. This ensures the TRIAC triggers evenly in both halves of the AC cycle, resulting in balanced power delivery to the load.

While the DB2 is a small signal device, it can handle repetitive peak currents of for short durations (10 ms at 50/60 Hz). This is sufficient to trigger most TRIACs in the Z0103, BT136, or BTA series. The following specifications are typical for the DB2/DB3

To help you effectively, I can offer the following: Here is a simplified sequence: A key advantage

AC waveforms demand balanced firing across both positive and negative half-cycles. The DB2 is optimized for a tight symmetry tolerance—typically ≤is less than or equal to

If you cannot find a DB2, consider these equivalents:

: DB-series DIACs are employed as starting elements in electronic ballasts for fluorescent lamps, where they help generate the high-voltage pulse needed to initiate the gas discharge in the tube.
