The silicon based regenerative diode shown in Fig. 1 acts as a unipolar device until the voltage across the device reaches 0.6 to 0.7V at 300K, after which it becomes a bipolar device. In the reverse direction, there is a small reverse peak current flowing in the device up to an approximate value of- IV due to the normally on-state behavior ofthe device. The device is turned-offafter this voltage, which re-instates that it needs some reverse voltage/current to turn-offthe device. As the voltage crosses an approximate value of -lV, the reverse peak current decreases to a very small value due to the regenerative action ofthe device. In Fig. 2(a), the region A exhibits that the device is in a bipolar state, region B exhibits that the device is in a unipolar state, region C exhibits the flow of a small reverse peak current through the device till an approximate value of -lV, region D exhibits that a very small reverse leakage current is flowing through the device and finally region E exhibits that the device is in break down condition.
