Datasheet Pdf 14: Diac Db2
The DB2 is a bidirectional trigger diode (DIAC) designed to switch Triacs and SCRs in power control applications, featuring a typical breakover voltage ( cap V sub cap B cap O end-sub
) between 28V and 36V. These components are essential for phase control circuits, such as light dimmers and motor speed controllers, and are commonly available through electronic component distributors. For comprehensive technical specifications, refer to the datasheet available from AllDataSheet Mouser Electronics DB3/DC34 AND DB4/DB6 - Mouser Electronics
However, the part number DB2 refers to a very common component manufactured by Fuji Electric and others, which is a Diode Bridge Rectifier (specifically a Single-phase Bridge Rectifier). It is often mistakenly called a "Diac" because of the phonetic similarity or a misunderstanding of the schematic symbol.
Below is a complete technical paper analyzing the Fuji Electric DB2 (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.
What is the Diac DB2?
The DB2 is a common bidirectional trigger diode (DIAC). It is typically used in phase control circuits (e.g., light dimmers, motor speed controllers) to trigger a TRIAC. Diac Db2 Datasheet Pdf 14
The "14" likely refers to one of the following:
- DB2-14 – A specific model number (less common, but some manufacturers use this for voltage variants).
- Breakover voltage of ~14V (some DB2 variants have VBO around 14-16V).
- Date code or lot number (not a feature).

I cannot directly access external files, databases, or specific PDFs such as a “Diac DB2 Datasheet PDF 14.” My capabilities do not include real-time browsing, retrieving documents from the internet, or opening proprietary or internal datasheets.
However, I can help you develop a professional review template for a DIAC (Diode for Alternating Current) datasheet (e.g., DB2, DB3, DB4 series). If you provide the key specifications from your PDF (e.g., breakover voltage, peak current, datasheet author, part number), I can analyze them. The DB2 is a bidirectional trigger diode (DIAC)

In the high-stakes world of enterprise database management, few components are as critical—yet as misunderstood—as the DIAC parameters in IBM Db2. If you’ve recently searched for a “Diac Db2 Datasheet Pdf 14” or “IBM Db2 14 DIAC documentation,” you are likely a database administrator (DBA) or system engineer preparing for a migration, tuning a high-transaction OLTP system, or troubleshooting deadlocks.
This article serves as an extensive datasheet-style breakdown of DIAC values in IBM Db2 Version 14 (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. What is the Diac DB2
Key features
- Function: Diac DB2 is a bidirectional semiconductor diode (diac) used to trigger triacs and silicon-controlled rectifiers (SCRs) in AC switching and phase-control circuits.
- Breakover voltage (VBO): Typically specified range suitable for small-signal and mains-phase control applications.
- Off-state leakage: Low microampere-level leakage below breakover.
- Package: Compact through-hole or surface-mount options, commonly in DO-35 or SOD-style packages depending on variant.
- Temperature range: Operating junction temperature typically from -40°C to +125°C.
- Reliability: High switching repeatability and long life for repetitive triggering in dimmers, motor controls, and timing circuits.
Why DIAC Matters in Db2 14
Db2 14 (the latest continuous delivery version as of recent years) introduces refinements in locking scalability, especially for large partitions and high-concurrency workloads. The DIAC parameters in Db2 14 determine:
- Lock escalation thresholds (from row-level to table-level)
- Timeout intervals for lock requests (similar to
LOCKMAXandLOCKTIMEOUT) - Claim/drain processing (for online schema changes and utilities)
- SKIP LOCKED DATA behavior (non-blocking reads)
Without proper DIAC tuning, your Db2 14 system may suffer from:
- Deadlocks and timeouts under peak load.
- Poor concurrency (excessive lock contention).
- Unexpected lock escalation causing performance collapse.
