Voltage surge and transient suppression in EV chargers
Anything powered by an external source of electricity needs to be protected from voltage transients and surges, as it is not a question of whether such hazards will occur, but rather how often they will occur (and of what severity they will be). As might be expected, there are internationally agreed-upon regulations for surge and... Read more »
Transient Voltage Suppressor Failure Analysis
Transient Voltage Surge Suppressors protect against transient voltage spikes that normally occur in less than one nanosecond (.000000001 second). The most common and inexpensive utilize one or more MOVs (Metal-Oxide Varistor). The effect of the MOV is to clamp the maximum voltage value at a specified level above the peak of the …

Transient Suppression Devices and Principles
10-103 Crowbar-type devices involve a switching action, either the breakdown of a gas between electrodes or the turn-on of a thyristor, for example. After switching on, they offer a very low impedance path which diverts the transient away from the parallel-connected
Transient Voltage Suppression in Automotive
In most cars, the main voltage rail system is 12V DC, which is powered by the rectified and regulated output of an alternator, as well as from the battery. The alternator is inductive, and therefore a potential source of transient voltages.
Protecting Sensitive Electronic Circuits Using a Transient Voltage Suppressor …
What Causes Transient Voltage Suppressor Diode Failure If the TVS diode is exposed to voltages or conditions beyond those it was designed for, it will fail. For example: to protect a port operating within a 0 – 5 V range, selecting a TVS diode with a breakdown voltage of 5 V is a good choice.
Introduction Unidirectional TVS Devices
