Will a power spike travel to parallel circuits?


I'm powering a relay and a device with an IC from the same power supply (12VDC), and they are wired in parallel. Will the spike caused by the coil when the relay activates potentially result in a spike in the parallel circuit?

I know that if the relay was actually wired in series with an IC or transistor, I would need to put a diode backwards across the coil leads, but is this necessary when there is nothing wired in series with the relay that could be damaged?

The spike caused when the relay de-energizes is going to go every where. It could turn the semiconductor material of the device controlling it into just so much more plain wire. That is why a diode is placed across the coil m of a relay to discharge the reverse voltage generated by the coil at turn off. The cathode of the diode will point towards the positive supply potential, while the anode is connected to the negative supply potential. Spikes, even in low voltage applications are very bad for the health of the other components.

The Diodes


The Diodes

High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

Revised and fully up-dated, the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. Elementary properties such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III-V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises, solutions, and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering, applied physics, and materials science.

In this book, I have optimized the growth of n and pGaN films, and high quality InGaN/GaN multiple quantum wells (MQWs) on sapphire (0001) substrate by a low pressure metalorganic chemical vapour deposition and have fabricated high brightness InGaN/GaN MQW lightemitting diodes (LEDs) under optimum conditions. To improve quantum efficiency which is generally poor in the conventional rectangularshaped QWs due to spatial indirect recombination induced by internal piezoelectric field, we proposed a possibility of quantum dot (QD) engineering with triangularshaped band structure in the InGaN/GaN QWs. The structural and optical properties of the InGaN/GaN MQWs with different threading dislocation densities were also investigated. The effects of Sidoped nGaN and Mgdoped pGaN layers on the electrical and optical properties of the InGaN/GaN MQW LEDs were investigated and optimized under various growth parameters.
