Diac Db2 Datasheet Pdf 14 Top Link

The DB2 is a bidirectional trigger diode (DIAC) typically used to trigger TRIACs in AC control circuits, such as lamp dimmers and motor speed controls. While the exact "DB2" part number is less common than its successors, it is functionally equivalent to or replaced by more modern standard parts like the DB3 or SMDB3. Technical Specifications (Reference: DB3 Series)

Since DB2 is often grouped with the DB3/DB4 series in manufacturer catalogs, the following specifications are the standard for this class of bidirectional trigger diodes: DIAC DB2 DIODE Datasheet(PDF) - ALLDATASHEET.COM

The DB2 is a bidirectional DIAC (Diode for Alternating Current) trigger diode, primarily used in conjunction with TRIACs for simplified gate control in AC switching applications. While specific datasheets for the exact "DB2" designation can sometimes be less common than its closely related counterparts like the DB3 or DB4, it shares the same core functionality and physical characteristics. Key Technical Specifications

This article provides a technical deep-dive into the Diac DB2 (Diode for Alternating Current), a critical bidirectional trigger device widely used in power control electronics. What is a Diac DB2?

A DIAC (Diode for Alternating Current) is a two-terminal semiconductor switch that remains in a high-resistance (off) state until a specific "breakover voltage" ( VBOcap V sub cap B cap O end-sub

) is reached. Once triggered, it switches to a low-resistance state, allowing current to flow in both directions. The DB2 is a specific variant, often manufactured by companies like STMicroelectronics and Shenzhen Luguang, known for its stability and precision in triggering thyristors.
