Application Note Protecting Low Current Loads in Harsh

... resistor. A TVS with lower power rating is able to handle the resulting current. In this case a 500 W suppressor, such as the SA28A TVS, replaces the 5 kW device, saving board space and cost. An SA28A was chosen in this example since its current rating for a 10/1000 µs pulse is 11 A, easily withstan ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
