Diacs, Sidacs from STMicroelectronics : 10 - Page 1

Diacs and Sidacs are bidirectional semiconductor devices used primarily in AC switching and triggering applications. Diacs, or Diode Alternating Current Switches, serve as trigger devices for triacs, allowing for smooth operation in dimmer switches and motor speed controls. Sidacs, or Silicon Diodes for Alternating Current, function similarly but offer a higher voltage breakdown, making them suitable for more demanding applications.

These components are essential in ensuring precise control and reliable performance in various electronic circuits. Renowned manufacturers like Littelfuse and STMicroelectronics produce Diacs and Sidacs with high-quality standards and excellent performance characteristics.

Incorporating Diacs and Sidacs into your designs enhances the efficiency and reliability of your AC control applications, providing essential functionality for phase control, light dimming, and motor control systems.
