When properly applied, this type of diode setup is an easy, inexpensive way to prolong the life of your inductive circuits. While many of the terms for this are used interchangeably, Chris McGrady highlights the term “snubber” in his article, as well as some variations on the concept we didn't explicitly discuss … See more When you power an inductive load, like a motor or relay, the current across the load will spike, until it drops down to a steady state. This behavior is the reason why such loads initially require a large amount of current, but then … See more The solution here, is to let the inductor “spin itself down” with a flyback diode. These are normal diodes, which are connected in parallel with an inductor’s (motor’s) two terminals. The diode is oriented in a reverse … See more Cushioning an inductor’s current change is generally a good thing, however, consider that in the case of a control relay, the goal is normally a near-instant controlled response.
