Abstract
An integrated overvoltage and overcurrent circuit protection device for use in telecommunication circuits. The integrated circuit protection device combines a overcurrent device such as a fuse and a overvoltage protection device such as a thyristor to respectively protect against overcurrent conditions and transient overvoltages. Integration of multiple devices in a common package ensures proper coordination and matching of the components, reduces the final product cost and reduces the physical space required on a telecommunications circuit for overvoltage and overcurrent circuit protection.
Claims20
An integral circuit protection device providing overcurrent and overvoltage protection for a circuit and configured to be connected to the circuit, the integral circuit device comprising:
- an overcurrent protection portion;
- an overvoltage protection portion disposed at one end of two opposing ends of the device;
- and
- a plurality of terminals for connecting the overcurrent protection portion and the overvoltage protection portion to the circuit, wherein the plurality of terminals are substantially disposed, respectively, at one of the two opposing ends.
An integral overvoltage and overcurrent protection device, comprising:
- an insulating housing having a first end and a second end and a hollow portion extending therebetween;
- a fuse element in the hollow portion;
- at least two terminations, a first termination on the first end of the housing, a second termination on the second end of the housing;
- an overvoltage protection portion on the second end of the housing.
