) is reached. Unlike a standard zener diode that conducts in one direction or breakdown clamps, the DB2 breaks down symmetrically in both the positive and negative directions.
The DB2 behaves like a "transistor without a base". It remains in a non-conductive state until the applied voltage exceeds its specific breakover threshold. Once triggered, its resistance drops sharply (negative resistance characteristic), allowing a pulse of current to flow to the gate of a TRIAC. Datasheet - DB3, DB4, SMDB3 - Diac - STMicroelectronics

The is a three-layer, two-terminal semiconductor device. Unlike standard diodes that restrict current flow to one direction, a DIAC acts as a bidirectional trigger diode. It remains in a non-conducting state until the applied voltage across its terminals reaches a specific threshold called the breakover voltage ( VBOcap V sub cap B cap O end-sub Diac Db2 Datasheet Pdf 14
While a direct PDF for the "DB2" may be elusive, here's a practical guide to finding or working with its specifications:
: Once the threshold is hit, the device "breaks over" and its resistance drops sharply, allowing a pulse of current to flow into the gate of a TRIAC or
, the DB2 remains a notable variant for specific legacy or low-threshold applications. Key Features & Technical Specifications According to industry datasheets (such as those from STMicroelectronics ON Semiconductor ) is reached

is a bidirectional trigger diode designed primarily for low-voltage triggering in AC control circuits, such as lamp dimmers and motor speed controllers. While modern designs frequently use the It remains in a non-conductive state until the
Your search for “Diac Db2 Datasheet Pdf 14” likely points to a technical document from IBM that consolidates all DIAC-related parameters for Db2 14. While I cannot directly embed a PDF file, I will detail the you would find in the official IBM Redbook, Knowledge Center, or Installation Guide under the Db2 14 for z/OS (or LUW) sections.
This is the most likely correct match for your query. Our search uncovered a PDF that aligns perfectly: the The file name is ibm_fm_db2_14.1.22.pdf . This document is a user guide and reference , effectively serving as the software's primary datasheet/manual for version 14.
A DIAC (Diode for Alternating Current) is a two-terminal, three-layer bidirectional semiconductor device. Unlike a standard diode, a DIAC does not conduct until its breakover voltage ( VBOcap V sub cap B cap O end-sub
