DEVICE PHYSICS
Static dV turn-on is a consequence of the Miller effect and regeneration (Figure 1). A change in voltage across the junction capacitance induces a current through it. This current is proportional to the rate of voltage change dV . It triggers the device on when it becomes large enough to raise the sum of the NPN and... |
