Within a MOSFET-based Class-D amplifier driving a highly inductive load (speaker), which consequence happens when exceeding the MOSFET's Safe Operating Area?

💡 Explanation

Thermal runaway leads to device failure because exceeding voltage or current limits within the Safe Operating Area causes increased power dissipation, creating a positive feedback cycle of heat. Therefore it leads to failure, rather than recovery, threshold shift, or oxide breakdown under typical usage.
