V = L Δ i Δ t V = Zener Voltage L = coil inductance di = 80mA Leaving dt Now you know the energy stored in the coil: E = 1 2 L i 2.
Selecting a zener diode for solenoid flyback suppression
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. As flyback diodes keep the current flowing for … See more WebNov 14, 2024 · Using a regular diode requires snaking an additional trace (for the solenoid power rail) through the layout, making it a lot more complicated. I don’t need to do that with a zener. The protection principle is different. With a regular diode you’re dissipating the flyback energy through the coil. hifi cycling
How Flyback Diodes Work – Snubber Diodes Explained Arrow.com
WebThe most common way to handle this voltage spike is to use “flyback diodes.” These aptly named diodes are typically just standard diodes, rated at many times the supplied voltage. These are used to create a … WebThe fly-back diode will be held at a constant temperature; diodes have a constant resistance in conduction when held at a constant temperature. … WebThe BTA54WS is a Schottky diode, but still in the parameter range. Schottky diodes are the fastest and good as well. It will be helpful in rapidly switching load but rather costlier than the cheap 1N400x series. Chosen breakdown voltage of the diode shall be 8 … hi-fi cruisin hattiesburg ms
