← TechnologyWhich malfunction indicates excessive reverse saturation current at BJT junction?
A)Thermal runaway at high temperature✓
B)Reduced switching speed exhibited
C)Increased collector-emitter voltage
D)Decreased base-emitter resistance onset
💡 Explanation
Thermal runaway occurs because increased temperature raises the reverse saturation current, leading to increased power dissipation via positive feedback, therefore producing progressively higher temperatures rather than stable operation under reverse bias at the junction.
