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:

Product Line

Max Rated dV/dt

Typical Application

|-------------|-----------------|--------------------|

HVCT8G N4700 (Single-Disc)	30 – 50 kV/μs	SiC inverter snubbers, motor drives
HVCT8G N750 (HF Optimized)	50 – 100 kV/μs	GaN converters, high-frequency resonant
HVCD Disc N4700	20 – 40 kV/μs	General-purpose fast switching
HVCD Disc Y5U/Y5V	10 – 25 kV/μs	Lower-frequency pulse applications

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.
