STMicroelectronics DB4 DIAC semiconductor with a maximum breakover voltage of 45 V and capable of handling a repetitive peak on-state current of 2 A is designed for gate triggering applications. This 2-pin device in a DO-35 through-hole package is optimized for use in motor control, light dimmers, and fluorescent lamp ballast circuits, functioning as an effective trigger diode with a fixed voltage reference.
The device features a low breakover current of 10 μA and symmetrical breakover voltage with only a 3 V difference across polarities, providing reliable and stable triggering with minimal power loss. It operates efficiently within a wide temperature range from -40°C to 125°C, allowing deployment in demanding industrial environments.
Its compact size, with a length of 4.5 mm and height of 2.75 mm, facilitates easy integration onto printed circuit boards using through-hole mounting. The repetitive peak off-state current is just 0.01 mA which ensures low leakage current and energy efficiency during operation.
Fixed breakover voltage for consistent triggering action. Repetitive peak on-state current supports robust switching loads. Through-hole DO-35 package for straightforward assembly. Wide operating temperature range suits industrial and automotive applications.
Low breakover current reduces power dissipation. Breakover voltage symmetry minimizes triggering variance. Minimal off-state leakage current enhances efficiency. Compact dimensions enable dense PCB layouts. Commonly used in triac and SCR triggering for lighting and motor control.
Environmentally compliant per ECOPACK®2 standards.
This DIAC is essential for professionals designing reliable power control circuits in industrial, manufacturing, HVAC, and lighting applications. It offers proven performance in controlling alternating current loads with precision and longevity.
