V. Selecting the Right Semiconductor Fuse: Critical Guidelines
Maximize protection with these engineering principles:
I²t Coordination
Fuse I²t ≤ 80% of semiconductor rating (e.g., for 30,000 A²s IGBT, select fuse with ≤24,000 A²s).
Voltage Derating
Fuse voltage rating ≥ 120% of system voltage (e.g., 1000V fuse for 800V EV bus).
Environment-Specific Materials
Ceramic/sand: High-vibration EVs or desert solar farms .
Epoxy-sealed: Marine or chemically aggressive environments .
