What type of ESD failure occurs when generated heat causes path breakdown?

• A. Voltage-induced
• B. Current-induced
• C. Catastrophic
• D. Intermittent

Answer: (B)

The type of ESD failure that occurs when generated heat causes path breakdown is categorized as current-induced failure. In this context, current flow through a component can generate a significant amount of heat. When an electrostatic discharge event occurs, and if the resulting current is strong enough, it can create localized heating which may exceed the material limits of the component, leading to breakdown of the path. This breakdown can manifest as a permanent failure that alters the characteristics of the component, often leading to complete non-functionality. Current-induced failures are typically associated with the direct thermal effects of high current transients. These transients can cause physical damage to the wiring, circuitry, or semiconductor junctions, resulting in a loss of functionality or reliability of the component. In contrast, voltage-induced failures relate more to high voltage events that can create arcing or dielectric breakdown without necessarily causing significant heating. Catastrophic failures refer to those that result in complete and immediate loss of function, while intermittent failures can come and go, potentially confusing the troubleshooting process, but they do not result from immediate heating effects as seen in current-induced failures.
