Which outcome occurs when a fast-acting solenoid valve experiences coil inductance exceeding the driver circuit's design limit?

💡 Explanation

When coil inductance exceeds the driver's limit, inductive kickback creates voltage spikes that exceed the transistor's breakdown voltage, causing its failure, because of energy stored in the inductance being rapidly discharged. Therefore transistor failure results, rather than stiction, erosion or noise which require alternate failure modes.
