14 Top — Diac Db2 Datasheet Pdf
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).

Recommended steps to obtain the official DB2 datasheet PDF:
- Visit STMicroelectronics’ website – They produce the STN (SOT-223) version of DB2.
- Search for "DB2 DIAC" on Diotec Semiconductor – They have a very clear DB2 datasheet in DO-35 glass package.
- Use EIC’s product database – Alternate source for DB2 in axial lead form.
Pro Tip: When you download the PDF, search inside the document for "VBO" and "32V". If the document does not list the 14 parameters above, it is either an incomplete translation or a counterfeit datasheet.
8. Output Pulse Rise Time (tr)
- Typical Value: 0.5 to 2 µs
- Significance: A fast rise time ensures clean, jitter-free triggering of the TRIAC gate.
What the DB2 Datasheet PDF Typically Contains (Table of Contents)
- Features: Bidirectional, symmetrical breakover voltage, low IBO.
- Mechanical Data: Dimensions for DO-35 (glass body, 4.5mm length, 2mm diameter) or SOT-23.
- Absolute Maximum Ratings: ITM, IPSM, Tj, Tstg.
- Electrical Characteristics: The "14 Top" list plus typical curves.
- Characteristic Curves (Critical for designers):
- VBO vs. Junction Temperature
- On-State Voltage vs. On-State Current
- Trigger Pulse Width vs. Current Capability
- Application Circuit: Typical DIAC-TRIAC phase control.
- Ordering Information: DB2-T (tape & reel), DB2-AP (ammo pack).
2. Breakover Current (IBO)
- Typical Value: 15 µA to 50 µA
- Significance: The small current flowing just before breakover. A lower IBO means higher sensitivity.
Part 3: How to Read the DB2 Datasheet PDF (Where to Find Legit Sources)
Searching for "diac db2 datasheet pdf 14 top" on Google often returns aggregated sites (Alldatasheet, Datasheet4U, etc.). While convenient, always cross-reference with the original manufacturer.
Top 14 Specifications from the DB2 Datasheet
The following are the 14 top parameters you will find on a standard diac db2 datasheet pdf.
9. Selection considerations
- VBO matching: Choose DIAC VBO matching gate trigger requirements of the TRIAC and desired firing angle.
- Voltage rating: Ensure VDRM/VRRM exceeds peak supply voltage plus margin.
- Current/surge capability: Match expected gate pulse currents and any potential transients.
- Package / mounting: Through-hole vs SMD per PCB design.
