Abstract: Commonly, a transient protection filter circuit is integrated between power sources and the circuits that follow to suppress voltage transients. Pre-existing transient protection filters are implemented such that when a transient is detected, transistors in the path become linear regulators. Instead, this invention uses bridge resistors to form a voltage divider to dissipate the extra power. The novelty of this invention is that it protects the load not by dissipating the extra power in front of the load as other transient protection filter circuits do, but by providing energy from the transient to the load through a resistor. This implementation solves the problem of thermal runaway that is commonly caused when transient \roltages are filtered by dissipating power within r the transistors in the path of the transient and the electric circuits after the transistors.
