This article serves as an extensive datasheet-style breakdown of DIAC values in (Db2 14). We will explore what DIAC means, how the parameters have evolved from previous versions, where to find the official PDF datasheet, and how to apply these settings for optimal performance and data integrity.
Upgrade to Db2 14 if your workload suffers from global lock escalation in partitioned tablespaces. Diac Db2 Datasheet Pdf 14
): The range of internal temperatures the diode can safely operate at, commonly -40 to +125°C. The safe temperature range for storing the component. C. Physical and Packaging Data
A proper datasheet should include:
Further reading: IBM Redbook “DB2 for i SQL Performance Diagnosis and Tuning” (SG24-8226) complements the Diac datasheet by explaining the underlying DB2 metrics that Diac visualizes.
Standard axial lead DO-35 glass package for through-hole mounting. Operational Characteristics There is – it’s often a mislabel or partial marking
from major manufacturers. Use DB3 datasheet as the functional replacement unless your component marking clearly indicates a different breakover voltage (check with a component tester or curve tracer).
Whether you are looking to download the official or seeking to understand the unique characteristics outlined in Page 14 of extended thyristor documentation, this technical overview covers the critical operational physics, electrical parameters, and circuit configurations you need. 1. What is a DIAC?
The construction of the standard DB2 components utilizes a hermetically sealed glass envelope.

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
The physical casing, often glass-sealed for hermetic protection. Peak Forward Current ( IFMcap I sub cap F cap M end-sub ): Maximum current in one direction. Reverse Leakage Current ( IRcap I sub cap R
The breakover voltage is symmetric for both positive and negative polarities, ensuring balanced AC performance. Breakover Voltage Symmetry ( ±plus or minus
