Solid-state circuit breakers use power semiconductor switching devices — typically MOSFETs, IGBTs, or silicon carbide (SiC) and gallium nitride (GaN) wide-bandgap devices — to provide overcurrent and fault protection without mechanical contacts, offering deterministic trip times in the microsecond range and compatibility with 28 V DC, 270 V DC, and emerging 540 V DC aerospace power architectures.
