What type of ESD failure leads to complete malfunction of the device?

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

Answer: (B)

The type of ESD failure that leads to complete malfunction of the device is catastrophic failure. This occurs when an electrostatic discharge event causes immediate and irreversible damage to the components of the device, resulting in a total loss of functionality. Catastrophic failures can often be linked to high voltages that exceed the damage threshold of sensitive electronic components, causing physical damage like melting or vaporization of materials, which render the device unusable. In contrast, other types of failures, such as current-induced, latent, or intermittent, do not typically result in the complete loss of function. Current-induced failure refers to scenarios where damage is caused by excess current, but not necessarily to the extent of complete device failure. Latent failure might cause a device to function initially but later fail due to accumulated damage over time. Intermittent failure implies that the device may function sporadically, creating unreliable performance but not a total failure. Therefore, catastrophic failure distinctly signifies a full and immediate loss of operational capability in a device due to ESD.
