Abstract
A circuit for attenuating a surge is disclosed that might include a conductor for receiving the surge, a capacitor, positioned along the conductor, for blocking the surge, and a gas tube having a first end coupled to the conductor and a second end coupled to a ground. The circuit might also include a transformer having a first wire and a second wire, the transformer being coupled to the conductor, a resistor coupled to the first and second wires of the transformer, a varistor coupled to the first wire of the transformer, and a diode coupled to the second wire of the transformer.

A circuit for attenuating a surge comprising:
- a conductor for receiving a signal and a surge induced overcurrent;
- a capacitor, positioned along the conductor, for blocking the surge;
- a gas tube having a first end coupled to the conductor and a second end coupled to a ground;
- a transformer having a core and first and second wires wound around the core, the transformer being coupled to the conductor and the core saturating when the surge induced overcurrent reaches the first wire;
- and
- a resistor coupled to the first and second wires of the transformer.
A surge suppression circuit having an input conductor for coupling to a signal line and an output conductor for coupling to equipment to be protected, the circuit comprising:
- a capacitor coupled between the input conductor and the output conductor;
- and
- a transformer having a first conductor coupled to the input conductor and a second conductor coupled to the output conductor.
A circuit for attenuating transient impulses comprising:
- an input port configured to receive a signal and a transient impulse having a leading portion and a trailing portion;
- a gas tube coupled to the input port and configured to divert the trailing portion of the transient impulse to ground;
- a capacitor coupled to the input port and configured to pass the signal and block the leading portion of the transient impulse;
- a transformer coupled to the input port and configured to pass the signal and the leading portion of the transient impulse;
- and
- a varistor coupled to the transformer and configured to divert a part of the leading portion of the transient impulse to ground.
