Diac Db2 Datasheet Pdf 14 Top [extra Quality] Jun 2026

: The voltage reaches the specific DB2 threshold (typically between 25V and 30V ).

) 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 diac db2 datasheet pdf 14 top

) compared to the more common DB3 or DB4 is required for circuit stabilization. : The voltage reaches the specific DB2 threshold

Now, the AC sine wave begins to rise.

: Its primary role is to provide a reliable, symmetrical trigger pulse to fire a TRIAC in AC power control applications. This setup is used in household dimmer switches, fan speed regulators, electric heater controls, and universal motor speed controls for power tools. The DIAC ensures the TRIAC fires cleanly and evenly at the desired point in each AC half-cycle. Its structure typically consists of three or five

), usually ±3V max, ensuring equal triggering on both AC half-cycles. IBOcap I sub cap B cap O end-sub
