← TechnologyWhich consequence results when thermal runaway occurs in a SiC MOSFET circuit?
A)Decreased switching related power loss
B)Lower on-state resistance threshold increase
C)Uncontrolled current threshold increase✓
D)Increased gate threshold voltage stability
💡 Explanation
Uncontrolled current increase happens as the MOSFET's on-resistance decreases with increasing temperature, driving further current through the device, resulting in more heat generation (thermal runaway); therefore, current escalates, rather than improving stability, because positive feedback overcomes gate control limits.
