Diac Db2 Datasheet Pdf 14 [portable] – Deluxe
The 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
Below is a complete technical paper analyzing the (often found in datasheets as DB2S, DB2M, or DB2G), which matches the "DB2" identifier and is typically available in the PDF format you requested. If you are actually looking for a Diac component (like the DB3), please see the note at the end.
This article provides an in-depth analysis of the , focusing on the 14 critical parameters that determine its performance, stability, and suitability for your application. 1. What is a Diac DB2?

"Because," Elias said, heading for the exit, "Pages 1 through 13 would have told us to replace the whole compressor for fifty grand. Page 14 told us the Diac just needed a five-cent wire to stop being paranoid."
Once the breakover voltage is hit, the device enters a negative dynamic resistance state, resulting in a sharp increase in current and a decrease in voltage drop—ideal for firing Triacs or SCRs. Glass Passivation:
The series is designed specifically for high-efficiency, reliable triggering of TRIACs in AC power control circuits, offering a lower voltage threshold compared to its counterparts like the DB3. 2. The Diac DB2 Datasheet: 14 Critical Parameters Explained

This paper provides a comprehensive technical overview of the DB2 series component. While often confused with a Diac (Diode for Alternating Current) due to nomenclature similarities, the DB2 is a standard single-phase silicon bridge rectifier. This document analyzes its electrical characteristics, thermal properties, mechanical dimensions, and common applications in power supply circuits.
I will structure the article as follows: If you are actually looking for a Diac
). Once triggered, the voltage across the device drops sharply, allowing a sudden, powerful pulse of current to pass through to the gate of a primary switching device.
You will most often find these components tucked away in everyday household electronics:
He worked quickly, the smell of rosin core solder filling the small room. He carefully soldered the tiny jumper wire onto the circuit board controlling The Behemoth.
