The DB2 DIAC is a two-terminal semiconductor device with a symmetrical structure, often compared to a transistor without a base connection. Structure: It typically features a three-layer ( ) or five-layer semiconductor stack. Terminals: The two electrodes are designated as (Main Terminals 1 and 2) or Anode 1 and Anode 2.

Understanding the technical nuances of the DB2 through its official PDF documentation is essential for designing reliable light dimmers, motor speed controllers, and ballast systems. This comprehensive guide covers the technical specifications, electrical parameters, and top design use cases found in the . Functional Overview and Operating Mechanism
(Leakage Current): The small current that flows through the DIAC before it breaks over ( Typically -40°C to +125°C. Tjcap T sub j According to standard manufacturer data, the DB2 generally
– If you confirm the manufacturer (e.g., STMicroelectronics, NXP, or a generic DB2 DIAC), I can point you to official sources.
If you cannot locate a DB2, consider these options:
They are very similar, and for many applications, they are functionally equivalent. The main difference is that SIDACs generally have higher breakover voltages (typically above 100V) and higher current handling capabilities.
