If you are an engineer or a student and need the official documentation, here are the best actionable steps to take: The DIAC acts as an open switch

), the device switches from an insulating state to a highly conductive state. This sudden drop in internal resistance causes a steep rise in current, producing a fast-rising voltage pulse ideal for firing the gate of a larger power semiconductor like a TRIAC. Key Electrical Technical Specifications

Before breakdown, a very small leakage current flows. This is specified at a voltage slightly below VBO and is typically very low, often maximum . A low leakage current ensures the DIAC does not unintentionally trigger the TRIAC under normal operating voltages.
