Core Functional Technology of DIACs and SIDACs

1. DIAC (Diode for Alternating Current) - Functionality: A DIAC is a two-terminal semiconductor device that exhibits a unique characteristic of conducting current only after a specific breakover voltage is reached. It is designed to operate in AC circuits, allowing it to switch on and off symmetrically in both directions. - Operation: The DIAC remains in a non-conducting state until the voltage across it exceeds its breakover voltage. Once triggered, it allows current to flow until the current drops below a certain holding level, at which point it turns off. This behavior makes DIACs ideal for applications requiring phase control. - Applications: Common applications include: - Light Dimmers: Adjusting the brightness of incandescent lamps by controlling the phase angle of the AC waveform. - Motor Speed Controls: Regulating the speed of AC motors in fans and other devices. - Triggering Circuits: Serving as a trigger for TRIACs in various control applications.

2. SIDAC (Silicon Diode for Alternating Current) - Functionality: Similar to a DIAC, a SIDAC is a two-terminal device designed for higher power applications. It also features a breakover voltage and conducts in both directions, making it suitable for AC applications. - Operation: The SIDAC remains off until the applied voltage exceeds its breakover voltage, at which point it conducts until the current falls below a specified threshold. This makes it effective for handling transient conditions. - Applications: Key applications include: - Overvoltage Protection: Protecting sensitive electronic components from voltage spikes. - Triggering SCRs: Used in power control applications to trigger Silicon Controlled Rectifiers (SCRs) for precise control of high-power devices. - Snubber Circuits: Protecting switching devices from voltage transients.

Application Development Cases

1. Light Dimming Circuits - Description: DIACs are integral to light dimming circuits, allowing users to adjust the brightness of incandescent lamps by controlling the phase angle of the AC waveform. - Effectiveness: This application demonstrates energy efficiency and extends the lifespan of bulbs by reducing the average power delivered to the lamp.

2. Motor Speed Control - Description: In fan speed controllers, DIACs enable variable speed control of AC motors by adjusting the phase angle of the voltage supplied to the motor. - Effectiveness: This application enhances user comfort and energy efficiency, allowing for tailored performance based on user preferences.

3. Overvoltage Protection - Description: SIDACs are commonly used in surge protection devices to clamp voltage spikes, safeguarding sensitive electronic components from damage. - Effectiveness: By rapidly switching on during overvoltage conditions, SIDACs prevent circuit damage, ensuring the reliability and longevity of electronic devices.

4. Triggering SCRs in Power Control Applications - Description: SIDACs can effectively trigger SCRs in applications such as lighting control, heating elements, and motor drives. - Effectiveness: This application highlights the precision control SIDACs provide in high-power applications, improving overall system performance and efficiency.

5. Snubber Circuits - Description: Both DIACs and SIDACs can be utilized in snubber circuits to protect switching devices from voltage transients. - Effectiveness: By absorbing voltage spikes, these devices help maintain circuit integrity, reducing the risk of failure and enhancing overall system reliability.
