← TechnologySuppose a transient voltage spike exceeds a Zener diode's reverse breakdown voltage. Which outcome relating to component failure occurs because of this?
A)Thermal runaway causes junction degradation✓
B)Increased capacitance filters high frequencies
C)Decreased resistance permits forward current
D)Reduced depletion width lowers bias voltage
💡 Explanation
The Zener diode experiences failure because in exceeding the breakdown voltage, the avalanche effect initiates thermal runaway, destroying the P-N junction rather than simply clamping the voltage. Therefore causing degradation; rather than acting beneficially.
