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 1):
A packaged overvoltage protection circuit comprising:\n a first semiconductor die, wherein the first semiconductor die comprises a breakover diode having a reverse breakdown voltage of at least four hundred volts; a second semiconductor die, wherein the second semiconductor die comprises a breakover diode having a reverse breakdown voltage of at least four hundred volts; a package housing that encloses the first and second semiconductor dice; a first package terminal; and a second package terminal, wherein the first and second semiconductor dice are coupled such that if a positive voltage of adequate magnitude is present between the second package terminal and the first package terminal then breakover of the breakover diodes in the first and second semiconductor dice occurs and a current flows in a current path from the second package terminal, through the breakover diode of the first semiconductor die, through the breakover diode of the second semiconductor die, and to the first package terminal, and such that if a negative voltage of nine hundred volts or less is present between the second package terminal and the first package terminal then neither of the breakover diodes of the first and second semiconductor dice suffers reverse breakdown.
