The DB2 works from junction temperature. Storage is wider (-55°C to +150°C). If your design runs hotter than 125°C, the breakover voltage will drift downward (negative temperature coefficient typical for DIACs).

This is the "ghost story" of the component. Once the DIAC breaks over at 32 volts, its internal resistance collapses. It actually lowers its voltage requirement to stay on. It enters a valley where it conducts easier than before. It is a one-way door; once you push the DIAC through that 32-volt wall, it tumbles down the other side, conducting freely until the current drops to almost nothing.

Imagine a quiet control room in a power station in the 1960s. An engineer is trying to dim a set of stadium lights. He adjusts a knob, expecting a smooth fade. Instead, the lights strobe and flicker. The TRIAC is confused; it doesn't know exactly when to fire.

This is the voltage across the DIAC when it is conducting. For DB3 devices, the typical VO is often , but datasheets for DC34/DB4/etc. show values around 5V as well. This low on-state voltage drop is why the DIAC is an efficient trigger.
