Diac DB2 Datasheet PDF 19
A diac is a two-terminal bidirectional device that can switch AC currents from a few microamperes to several amperes. It is often used as a trigger device for triacs, thyristors, and other power control devices. A diac has a breakover voltage, which is the minimum voltage required to turn it on and conduct current in both directions. The breakover voltage of a diac depends on its type and specifications.
One of the common types of diacs is the DB2 diac, which is manufactured by STMicroelectronics. The DB2 diac has a breakover voltage range of 28 V to 36 V, and a maximum peak pulse current of 2 A. The DB2 diac is packaged in a DO-35 glass envelope, which has a diameter of 1.9 mm and a length of 4.8 mm. The DB2 diac can be used for various applications, such as lamp dimmers, motor speed controllers, and ignition circuits.
The datasheet of the DB2 diac provides detailed information about its electrical characteristics, ratings, package dimensions, and typical performance curves. The datasheet also includes some application circuits that demonstrate how to use the DB2 diac as a trigger device for triacs and thyristors. The datasheet can be downloaded as a PDF file from the STMicroelectronics website or from other online sources . The PDF file has 19 pages and a file size of 62 KB.
The DB2 diac is a simple but useful device that can help to control AC power devices with low cost and high reliability. By reading the datasheet of the DB2 diac, one can learn more about its features, specifications, and applications.
