The following data is derived from standard manufacturer datasheets (e.g., Fuji Electric, Rectron, Good-Ark).
Used in the input stage of Switched-Mode Power Supplies (SMPS) for consumer electronics (TVs, monitors, audio equipment). It rectifies the mains voltage (stepped down by a transformer) into a DC bus voltage.
The DIAC DB2 is a bidirectional trigger diode designed specifically to operate in conjunction with Triacs and SCRs. It functions as a voltage-sensitive switch that remains non-conductive until a specific breakover voltage is reached, at which point it allows current to flow in either direction. Core Specifications of the DB2 DIAC
The DB2 is often grouped with similar models like the DB3 or DB4, but it has distinct electrical parameters optimized for triggering. Typical Value / Range Breakover Voltage ( VBOcap V sub cap B cap O end-sub ) 28V to 36V (typically 32V) Breakover Current ( IBOcap I sub cap B cap O end-sub ) Maximum 50µA to 100µA Peak Pulse Current ( ITRMcap I sub cap T cap R cap M end-sub ) Output Voltage ( VOcap V sub cap O ) Minimum 5V Rise Time ( ) Maximum 1.5µs to 2µs Operating Temperature -40°C to +125°C Key Features STMicroelectronicshttps://www.st.com Datasheet - DB3, DB4, SMDB3 - Diac - STMicroelectronics Diac Db2 Datasheet Pdf 14
The DIAC DB2, often representing standard DB-series bidirectional trigger diodes, typically features a breakover voltage of 28V to 36V, a maximum breakover current of 50µA to 100µA, and is available in axial (DO-35) or SMD (SOD-123/SOT-23) packages. These components are primarily used to trigger TRIACs in AC power control applications like dimmers and motor speed controls. For technical specifications and PDF datasheets, visit AllDatasheet.

"Diac Db2 Datasheet Pdf 14" is a common remnant of automated spam or pirated PDF index searches rather than a real, singular electronic component. In the world of power electronics, the component you are looking for is a The following data is derived from standard manufacturer
(Diode for Alternating Current), and the most famous part families associated with it are the DB3, DB4, and SMDB3 series produced by manufacturers like STMicroelectronics
A complete overview of DIACs, their typical datasheet specifications, and their practical use in electronic circuits is detailed below. What is a DIAC?
is a bidirectional trigger diode designed specifically to trigger thyristors, such as TRIACs. It does not conduct current until the voltage applied across it reaches a specific threshold known as the Breakover Voltage ( cap V sub cap B cap O end-sub The DIAC DB2 is a bidirectional trigger diode
. Once this threshold is crossed, the device enters a state of negative resistance, causing a sharp drop in voltage and a sudden pulse of current. Standard Specifications Found in DIAC Datasheets
While specific part numbers vary, standard DIACs (like the DB3) share highly similar electrical profiles: What is Bootstrap? - „ZBYMAR” Mariusz Błażejewicz
The DB2 is a bidirectional trigger diode (DIAC) designed to switch Triacs and SCRs in power control applications, featuring a typical breakover voltage ( cap V sub cap B cap O end-sub
) between 28V and 36V. These components are essential for phase control circuits, such as light dimmers and motor speed controllers, and are commonly available through electronic component distributors.
