If you require a , that component does not exist in standard DB2 series. You may need a SIDAC (e.g., K2400 series) or a custom trigger diode. Please re-check the marking on your physical component – it may be DB3 with "14" as a lot code.
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).

| Possible Meaning | Explanation | |----------------|-------------| | | "14" printed on top of a DO-35 or DO-41 glass body indicates manufacturing year (e.g., 2014) or week 14. It is not the breakover voltage. | | 2. Breakover Voltage of ~14V | This is non-standard . Standard DIACs are 28-42V. A 14V device might be a special SIDAC or a low-voltage trigger diode (rare). Check the marking fully – is it "B14" or similar? | | 3. TO-14 Package? | There is no TO-14 package for DIACs. DIACs are in DO-35 (axial leaded glass) or SOT-23 (SMD for DIAC arrays). |

The remains a fundamental component for AC switching and phase control. By focusing on the "diac db2 datasheet pdf 14 top" specifications, you now have a complete reference—from breakover voltage to thermal resistance—to confidently integrate this device into your next dimmer, motor controller, or power regulator.
