(Diode for Alternating Current) is a bidirectional trigger diode designed primarily for AC power control applications. It belongs to the thyristor family and is widely used for triggering SCRs (Silicon Controlled Rectifiers) and TRIACs in circuits such as lamp dimmers, motor speed controllers, and heaters. 1. Device Architecture and Symbol
Based on standard industry DIAC datasheets from manufacturers like STMicroelectronics, here are the typical parameters for this series: Breakover Voltage ( VBOcap V sub cap B cap O end-sub diac db2 datasheet pdf 14 top
) is reached. Once triggered, it switches to a low-resistance state, allowing current to flow in both directions. The DB2 is a specific variant, often manufactured by companies like STMicroelectronics and Shenzhen Luguang, known for its stability and precision in triggering thyristors. Top Technical Specifications (Datasheet Summary) (Diode for Alternating Current) is a bidirectional trigger
However, I cannot directly retrieve or attach PDF files. But I can provide you with a detailed technical report based on the standard DB3 / DB4 / DB2 DIAC family specifications. If the "14" refers to a voltage variant (e.g., 14V breakover), that is unusual because most DIACs are ~28-42V. I will clarify this. Could you share the manufacturer name
