← ScienceWhich outcome occurs when reverse bias voltage increases on a tunnel diode beyond peak point?
A)Tunneling current decreases exponentially✓
B)Ohmic current increases linearly
C)Capacitance becomes independent of voltage
D)Avalanche breakdown occurs abruptly
💡 Explanation
When the reverse bias voltage increases on a tunnel diode, the energy bands misalign further, reducing the number of available states for tunneling, causing the tunneling current to decrease exponentially. Therefore, tunneling current decreases rather than ohmic increase, constant capacitance, or avalanche breakdown which depend on different mechanisms.
