Bi-Directional Diac (DB3) 1Pcs

The DB3 is a two-terminal, bidirectional, three-layer semiconductor diode (DIAC) used primarily to trigger TRIACs and thyristors in AC power control circuits, such as dimmers and motor speed controllers. It operates by remaining in a high-impedance state until the voltage exceeds a breakover threshold (typically 32 v)

Key Features and Specifications:

• Function: Bidirectional trigger diode (conducts in both directions).
• Breakover Voltage (32v)
• Applications: Light dimmers, motor speed controllers, fluorescent lamp ballasts, and AC power management.
• Package: Common in axial leaded DO-35
