FAE Expert Insights
"In my 15 years supporting power electronics designs, I've found Mersen high-speed fuses to be among the most reliable for semiconductor protection. The HS series consistently delivers the low I2t values needed for modern IGBT modules. I particularly appreciate the consistent performance across temperature ranges - critical for industrial applications. For sizing, I always recommend comparing fuse clearing I2t to the IGBT's withstand rating with at least 20% margin. The HS200-500 is ideal for 100-150kW power converters using 600V IGBT modules."

Frequently Asked Questions
What is the typical opening time of this high-speed fuse?
The HS200-500 typically opens in less than 1 millisecond at 10x rated current (2000A). At lower overcurrents (2-3x rating), opening time may be 5-20ms. The ultra-fast opening limits let-through I2t to protect semiconductors. Actual opening time depends on fault current magnitude - higher currents result in faster opening.
Verify opening time meets your semiconductor protection requirements. Contact our FAE for time-current curves.
How do I calculate the I2t for coordination with my IGBT?
IGBT withstand I2t is typically specified in the datasheet at 10ms pulse width. For coordination: 1) Find IGBT I2t withstand from datasheet; 2) Find fuse clearing I2t at same fault current from time-current curve; 3) Ensure fuse I2t < 0.8 x IGBT I2t (20% margin); 4) Consider worst-case temperature. Example: If IGBT withstand is 50,000 A²s, fuse clearing should be <40,000 A²s.
Compare fuse clearing I2t to IGBT withstand with 20% margin. Use manufacturer curves for accurate values.
