The DB2 DIAC (Diode for Alternating Current) is a bidirectional trigger diode commonly used in power control circuits, such as light dimmers and motor speed controllers. It acts as a switch that stays off until a specific "breakover voltage" is reached, at which point it suddenly conducts current in either direction.

| Possible Meaning | Explanation | |----------------|-------------| | 1. Date Code / Lot Number | "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). | diac db2 datasheet pdf 14 top
