Diac Db2 Datasheet Pdf 14 Top
The is a bidirectional trigger diode designed to control AC power circuits by acting as a highly efficient voltage-sensitive switch. Widely utilized alongside TRIACs and SCRs, this compact component provides the precise pulse required to spark thyristors into conduction at specific points in an alternating current cycle.
Resistant to false triggering from noise, crucial in industrial applications.
Because it operates identically in both forward and reverse directions, it is ideal for alternating current (AC) environments. DB2 DIAC Key Specifications and Parameters
: The ST DB3/DB4 Datasheet is the industry standard for this class of DIAC. diac db2 datasheet pdf 14 top
The DB2 DIAC is a two-terminal semiconductor device with a symmetrical structure, often compared to a transistor without a base connection. Structure: It typically features a three-layer ( ) or five-layer semiconductor stack. Terminals: The two electrodes are designated as (Main Terminals 1 and 2) or Anode 1 and Anode 2.
. The voltage drop when the device transitions from breakover to an on-state current of 10mA. A higher drop yields a cleaner pulse output.
If the search returns zero results for DB2, use "DB3" as STMicroelectronics merged DB2 into the DB3 family. The technical datasheet PDF is identical. The is a bidirectional trigger diode designed to
Triggering device for Triacs and SCRs in phase-control circuits.
) enclosed in a hermetically sealed case. Unlike a standard asymmetric diode, the DIAC exhibits identical, symmetrical electrical characteristics in both the forward and reverse directions.
The DB2 is a member of the (Diode for Alternating Current) family, a bidirectional trigger diode that acts as a gatekeeper. For decades, these tiny, glass-encapsulated components have been the silent partners to TRIACs in almost every household light dimmer and ceiling fan speed controller. Because it operates identically in both forward and
To obtain the :
If you are searching for the “diac db2 datasheet pdf 14 top” keyword for an engineering project or for stocking components, use the table above as your quick‑reference datasheet. For additional technical support, consider ordering a DB3 from a major distributor and testing it in your circuit – the performance will be indistinguishable from the DB2.
The most common use of the DB2 is to provide a sharp, positive or negative pulse to the gate of a TRIAC. This determines the exact phase angle at which the TRIAC starts conducting in an AC waveform. 2. AC Motor Speed Control
