A DIAC is a two-terminal semiconductor device that acts as a switch, remaining non-conductive until a specific breakover voltage cap V sub cap B cap O end-sub

You cannot test it with a standard multimeter's continuity or diode test. You need a variable DC power supply and a resistor. Connect the DIAC in series with a resistor, slowly increase the voltage, and measure the voltage across the DIAC. You will see it quickly "break over" and conduct once it reaches its VBO. diac db2 datasheet pdf 14 top

Understanding a DIAC requires analyzing its symmetric, bidirectional turn-on behavior. When the voltage across the device reaches the breakover threshold, it drops into a low-voltage "on-state," sending a sharp current pulse to trigger a thyristor or TRIAC. Breakover Voltage ( VBOcap V sub cap B cap O end-sub

Understanding these 14 key specifications allows an engineer to confidently integrate a DB2 into a design or identify a suitable substitute, such as the readily available . Its simplicity, low cost, and effectiveness continue to make the DB2 DIAC an integral component in a vast array of electronic devices, from everyday light dimmers to specialized industrial equipment. : As these links may change, always search for site:st

The DB series DIACs are manufactured with a hermetically sealed, glass-passivated construction. This provides excellent protection against environmental contaminants (moisture, dust) and ensures long-term reliability and stable electrical performance over the device's lifetime.

A DIAC acts as a bidirectional switch that conducts current only after its breakover voltage ( cap V sub cap B cap O end-sub is reached. RS Components Replacement is the industry standard substitute for the DB2. Connect the DIAC in series with a resistor,
