Which device can protect semiconductor components against transient voltages?

A snubber circuit is designed specifically to protect semiconductor components from transient voltages, such as voltage spikes that can occur during switching. These transients can cause significant damage to sensitive devices like transistors and diodes. A snubber typically consists of a resistor and capacitor in series, which work together to absorb the high-energy spikes and dissipate the energy safely, thus preventing it from reaching the semiconductor components. This is crucial in maintaining the integrity of electronic devices and extends their lifespan.

While other devices listed may have protective functions in different contexts, they do not specifically address voltage transients in the same effective manner as a snubber circuit. Fuses are used for overcurrent protection, inductors can help filter noise but do not inherently protect against transients, and pushbutton switches are simple mechanical components with no protective function for voltage transients. Therefore, the snubber circuit is the most suitable option for this purpose, making it the correct choice.
