Diac Db2 Datasheet Pdf 14 Top

: The ST DB3/DB4 Datasheet is the industry standard for this class of DIAC.

Unlike a diode, a DIAC does not have a gate terminal. It breaks down and conducts in both positive and negative half-cycles of an AC waveform, making it ideal for AC power control. Core Technical Features

) has been momentarily reached. Manufacturers like STMicroelectronics have historically produced these hardware blocks to simplify gate control logic. diac db2 datasheet pdf 14 top

(Output Voltage): The voltage across the DIAC during conduction (

The is a specialized, bidirectional semiconductor device primarily used as a trigger for TRIACs in AC power control circuits. While the DB3 is arguably the most common, the DB2 is a crucial variant designed for specific breakover voltages and low-power triggering applications.

The DB2 has a (typically between 30V and 34V). This symmetry is crucial for AC applications, ensuring the DIAC triggers at the same voltage magnitude on both half-cycles. A poorly matched DIAC introduces even-order harmonics and flicker in dimmers. Core Technical Features ) has been momentarily reached

) : Max at half the breakover voltage, ensuring zero accidental triggers when the circuit is idle. Mechanical Packages and Form Factors

The DB2 serves as a starting element in electronic ballasts for fluorescent lighting. 5. Heat Control Circuits
