A DC surge protection circuit for protecting hardware from surges. During operation when no surge condition is present, the circuit passes signals from an input to an output through an inductance. When a surge is present, the circuit conducts a portion of the surge through at least one diode and diverts the surge to a ground node. A gas tube begins to conduct a portion of the surge above a first voltage level after the at least one diode first begins to conduct. A first MOV begins to conduct a portion of the surge above a second voltage level after the gas tube begins to conduct. The circuit may include a status portion. The circuit may be within an enclosure for plug-in to a motherboard or within an enclosure of an in-line connector for connection with a cable. The circuit may be configured to attach directly to a frame.

DC power surge protector

A surge suppressor device includes a first housing defining a first cavity, input and output conductors disposed in the first cavity of the first housing, a capacitor connected in series with the input conductor and the output conductor, a first spiral inductor having an inner edge connected to the input conductor and an outer edge and a second spiral inductor having an inner edge connected to the output conductor and an outer edge. The surge suppressor device further includes a second housing defining a second cavity and connected to the first housing, a feed-through connecting the first cavity to the second cavity, a non-linear protection device positioned in the second cavity of the second housing and a first electrical wire passing through the feed-through and connecting the outer edge of the first spiral inductor to the non-linear protection device.

DC pass RF protector having a surge suppression module

A surge protection circuit to reduce capacitance inherent of standard diode packaging and to improve voltage clamping reaction speeds under high surge conditions. The surge protection circuit has a coil having a first end and a second end and a diode cell having a top layer, a center diode junction, and a bottom layer. The top layer is directly connected to the second end of the coil and the bottom layer is directly connected to a ground. The diode cell has no wire leads.

DC and RF pass broadband surge suppressor

A surge protection device is disclosed that includes an input path for receiving an rf signal, dc power, and a surge, an output path for propagating the rf signal, and a dc blocking device coupled in series between the input path and the output path. The surge protection device also includes a first inductor coupled to the input path for isolating the rf signal and providing a path for the dc power, a gas tube coupled to the first inductor for routing a portion of the surge to a ground plane, a second inductor coupled to the first inductor for providing a path for the dc power, and a metal oxide varistor coupled to the second inductor for routing a portion of the surge to the ground plane. Furthermore, the surge protection device includes a third inductor coupled to the second inductor for providing a path for the dc power, a diode coupled to the third inductor for routing a portion of the surge to the ground plane, and a fourth inductor coupled to the third inductor for providing a path for the dc power to the output path.
