Abstract:
In a first embodiment, an ultra-fast breakover diode has a turn on time T ON  that is less than 0.3 microseconds, where the forward breakover voltage is greater than +400 volts and varies less than one percent per ten degrees Celsius change. In a second embodiment, a breakover diode has a reverse breakdown voltage that is greater, in absolute magnitude, than the forward breakover voltage, where the forward breakover voltage is greater than +400 volts. In a third embodiment, a string of series-connected breakover diode dice is provided, along with a resistor string, in a packaged circuit. The packaged circuit acts like a single breakover diode having a large forward breakover voltage and a comparably large reverse breakdown voltage, even though the packaged circuit includes no discrete high voltage reverse breakdown diode. The packaged circuit is usable to supply a triggering current to a thyristor in a voltage protection circuit.

Claim (Index 9):
A packaged overvoltage protection circuit comprising:\n a first package terminal; a second package terminal; a plurality of semiconductor dice, wherein each of the semiconductor dice comprises a breakover diode, wherein the breakover diode has a forward breakover voltage, wherein the breakover diode has a reverse breakdown voltage whose absolute magnitude is greater than the forward breakover voltage, wherein the plurality of semiconductor dice are coupled in series between the first and second package terminals, and wherein the breakover voltage is at least four hundred volts; a plurality of resistors, wherein the resistors are coupled in series; and a package housing that encloses the plurality of semiconductor dice and the plurality of resistors, wherein the package housing encloses no semiconductor die other than said plurality of semiconductor dice.
