摘要： A semiconductor component (4) is provided which is suitable for limiting transient voltages on the supply lines of a system having at least three supply lines, one of the supply lines (252) being a current sink. The semiconductor component comprises at least three input means (251,252,253) for connection to respective ones of the supply lines, and a respective multi-junction diode (200,210,220) for each input means (251,252,253) having a threshold voltage at which it changes from a high-impedance state to a low-impedance state. Each multi-junction diode (200,210,220) is connected in the same sense between a respective one of said input means (251,252,253) and a common terminal (250), and is paired with a respective further diode connected in shunt with it and in the opposite sense to it. One pair (210) of the diodes, being said pair connected to said current sink, has current capacities substantially equal to the combined current capacities of the other pairs of diodes (200,220) and each of the diodes is a diode having a single PN junction. A doped region (202,212,222) of the semiconductor body is common to all the diode pairs.

摘要： An overvoltage protector suitable for protecting conductors comprises first, second and third at least bipolar protection elements (132, 134, 136). A first electrode of each protection element is connected to a common node (138). A second electrode of the first protection element (132) and a second electrode of the second or third protection elements (134, 136) are suitable for connection to a conductor to be protected. The first and third elements (132, 136) have breakdown conduction characteristic in one direction and diode conduction characteristic in the other, and the second element (134) has breakdown conduction characteristic in both directions, wherein the respective first electrodes of the first and third elements (132, 136) are of the same polarity.

摘要： An overvoltage protection circuit for preventing voltage and current overload on a telephone line conductor (11, 13) to prevent damage to a SLIC (22) has a first SCR (47) for connecting the conductor to a reference potential (42) and a first trigger means (D1, TR5, R1) operable to switch the SCR from a first, OFF state to a second, ON state. The trigger means (D1, TR5, R1) is voltage-triggered by voltages exceeding a first magnitude on said conductor and current-triggered by voltages exceeding a second magnitude on said conductor, thereby to provide overvoltage protection at two discrete voltage magnitudes.

摘要： A semiconductor device having two or more p-n junctions, being in particular a bipolar transistor or a thyristor. The device has a gold ion implant (14) in a region of the device between two of or the two p-n junctions, which region is the base (2) in the case of a bipolar transistor, located away from the current carrying active region of the device. The device has a low resistance and may be turned off rapidly because the implanted gold provides recombination centres which act as a sink for carriers drawing them from the active region.
