Diac Db2 Datasheet Pdf 14 Top Better May 2026
Headline: 🔍 Resource Share: DIAC DB2 Datasheet & Technical Breakdown
Looking for the official specs on the DB2 DIAC? If you are designing triggering circuits for TRIACs or working on AC phase control, this component is a staple. Here is the lowdown on the "Top 14" search query and where to find the PDF.
📄 The Datasheet (PDF) If you are looking for the PDF, you can usually grab the official document directly from major semiconductor distributors. Look for the "DB2" series (often manufactured by names like STMicroelectronics, ON Semiconductor, or Littlefuse). diac db2 datasheet pdf 14 top
- Key Spec to look for: Breakover Voltage (typically 28V–36V) and Breakover Current.
⚡ Why the DB2 is a Top Choice The "DB2" is often ranked as a top component for through-hole designs because:
- Symmetry: It offers high symmetry in breakover voltages, ensuring precise triggering for AC circuits.
- Reliability: Excellent stability over temperature ranges.
- Application: Ideal for lamp ballasts, motor speed controls, and light dimmers.
🛠️ Engineering Note While searching for "14" in relation to this datasheet, many engineers often cross-reference the pinout. If you are laying out a PCB, ensure you are referencing the DB2 pinout (usually a DO-35 or DO-41 glass package depending on the specific variant) and not confusing it with the DB3 (which has different breakover voltage specs).

1. Objective
To provide the critical electrical and physical specifications of the DB2 DIAC (bidirectional trigger diode), typically used in TRIAC phase control circuits. This report addresses the common request for a "datasheet PDF" and explains the "14 top" marking.
9. Summary & Conclusion
| Your Query | Answer | |------------|--------| | DB2 DIAC | Standard bidirectional trigger diode, V_BO = 28–36V | | Datasheet PDF | Available from ST, Diotec, etc. Search "DB2 DIAC datasheet" | | "14 top" meaning | Likely a date code (e.g., week 14 of 2014 or 2024), not 14V breakover | | Package | DO-35 (not TO-14). TO-14 does not exist for DIACs |
7. Typical applications & circuits
- Lamp dimmers: With potentiometer and TRIAC for phase-angle control.
- Motor speed controls: Small AC motors using TRIAC-based controllers.
- Overvoltage protection: As part of trigger networks for crowbar or protection circuits.
- Relaxation oscillators: In timing circuits when combined with resistors/capacitors.
8. Equivalent Parts
| Replace DB2 with: | Reason | |-------------------|--------| | DB3 | V_BO = 28-36V (identical spec) | | DB4 | V_BO = 35-45V (slightly higher) | | HT-32 | V_BO = 28-36V |
