Do Fuses Blow When a TVS Diode Fails?
Discover whether a fuse will always blow when a TVS diode fails, and learn how short circuits, open circuits, and degradation affect circuit protection reliability. In circuit protection design, fuses and TVS diodes often work side by side: one handles overcurrent protection, while the other focuses on dealing with voltage transients. In real-world applications and failure analysis, many engineers naturally ask a straightforward question: when a TVS diode fails, will the fuse placed in front of it definitely blow?
