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 12):
An apparatus comprising:\n a first package terminal; a second package terminal; and means for blocking substantially all current flow from the second package terminal to the first package terminal for positive voltages less than a first voltage between the second and first package terminals, for initiating conduction of a breakover current from the second package terminal to the first package terminal if a positive voltage equal to the first voltage becomes present between the second and first package terminals, and for blocking substantially all current flow from the first package terminal to the second package terminal for negative voltages less than a second voltage between the second package terminal and the first package terminal, wherein the absolute magnitude of the second voltage exceeds the first voltage, wherein the first voltage is at least nine hundred volts, wherein the means comprises no semiconductor die other than a plurality of semiconductor dice, and wherein each die of the plurality of semiconductor dice comprises a breakover diode.
