Diac DB3

The Diac DB3 is a type of semiconductor diode known for its ability to switch between high and low resistance states with minimal voltage change. This characteristic makes it suitable for use in triggering and switching applications. The DB3 is commonly utilized in phase control circuits, such as those found in light dimmers, motor speed controls, and temperature control systems.

Key Features:

1. Breakover Voltage: The Diac DB3 has a well-defined breakover voltage, typically around 30V to 40V. When the applied voltage exceeds this threshold, the Diac switches from its high-resistance state to a low-resistance state, allowing current to flow.
2. Switching Speed: The Diac exhibits fast switching capabilities, making it ideal for applications requiring rapid on-off transitions. This feature is crucial in applications like triac triggering where timing precision is necessary.
3. Current Handling: Each Diac DB3 can handle moderate currents, typically up to 1A. This capability makes it suitable for a variety of power control applications.
4. Compact Package: The Diac DB3 is housed in a compact, robust package that ensures durability and ease of integration into electronic circuits. Its small size allows it to fit into space-constrained designs.
5. Temperature Stability: The Diac DB3 offers good temperature stability, maintaining consistent performance across a range of operating temperatures. This stability is essential for applications subject to varying environmental conditions.

Applications:

• Phase Control: Used in dimmer switches for controlling the brightness of lights by varying the phase angle of the AC signal.
• Motor Speed Control: Applied in circuits for adjusting the speed of electric motors.
• Temperature Regulation: Utilized in temperature control systems where precise switching is required.

Pack Details:

This pack contains five Diac DB3 components, providing a sufficient quantity for prototyping and production needs. The availability of multiple units ensures that users have backups in case of component failure or for use in multiple projects.

In summary, the Diac DB3 is a versatile and reliable component designed for efficient switching and control in various electronic applications. Its characteristics make it an essential part of modern electronic circuits where precise control of electrical signals is crucial.
