Can HVC components handle high dV/dt stress in fast-switching converters?

Yes — HVC capacitors are specifically characterized for high dV/dt (rate-of-voltage-change) capability, a critical parameter for modern wide-bandgap semiconductor (SiC/GaN) converter designs where switching edges can exceed 50-100 kV/μs:

Exceeding rated dV/dt causes internal dielectric stress leading to premature aging or catastrophic failure. HVC recommends applying a safety margin of ≥ 2× between maximum expected circuit dV/dt and component rating. For SiC/GaN designs pushing beyond 100 kV/μs, contact HVC engineering for custom high-dV/dt qualification on selected part numbers.
