Which outcome occurs when thermally-induced electron-hole pairs cause increased current in a silicon diode?

A)Thermal runaway destroys the diode
B)Zener breakdown voltage increases
C)Avalanche effect becomes more stable
D)Reverse saturation current decreases

💡 Explanation

Thermal runaway occurs because increased temperature leads to more electron-hole pairs, increasing current; the increased current raises the diode's temperature, leading to further electron-hole generation. Therefore, device destruction happens rather than lower current or a more stable breakdown, at lower temperatures.
