The device that protects the PCM and other electronic components from the voltage spike created in the windings of a solenoid, relay, or magnetic clutch when they are turned off is called a ______.
A)filter choke
B)clamping diode
C)suppression capacitor
D)voltage divider

Question

Quizplus · Accepted Answer

A clamping diode, also known as a flyback diode, is used to protect electronic components from voltage spikes by providing a path for the spike current when an inductive load like a solenoid or relay is turned off, thus preventing damage to the PCM and other sensitive electronics.
