High Speed Semiconductor Fuse: Precision Protection for Demanding Applications
When safeguarding high-power systems like electric vehicle (EV) battery packs, charging stations, or renewable energy inverters, every millisecond counts. Our High Speed Semiconductor Fuse is engineered to deliver ultra-fast circuit protection (<1ms) while handling extreme voltages up to 1,000V DC and currents exceeding 2,000A. Designed for reliability in automotive and industrial environments, this fuse combines precision engineering with IATF 16949-certified quality to prevent catastrophic failures in semiconductor devices.

Why Our High Speed Semiconductor Fuse Stands Out?
1. Ultra-Fast Protection for Critical Systems
Our fuse interrupts fault currents in under 1 millisecond—critical for protecting silicon carbide (SiC) and gallium nitride (GaN) semiconductors in EVs and fast-charging infrastructure. This rapid response minimizes thermal damage, even during 20kA+ surge events.
2. Built for Automotive & Industrial Extremes
With a water-cooled design and vibration-resistant construction, our fuses operate flawlessly in environments ranging from Arctic cold to desert heat. They’re proven in 800V EV battery systems and solar inverters with zero performance drift over 10+ years.
3. Customizable Solutions
Need a specific voltage rating or form factor? We adjust parameters like:
- Current capacity (up to 2,000A)
- Terminal configurations
- Cooling methods (air/water)
Applications
- EV Battery Packs: Safeguard 400V–800V systems against short circuits.
- DC Fast Chargers: Handle 500A+ currents in liquid-cooled charging piles.
- Solar/Wind Inverters: Protect IGBT modules in 1,500VDC renewable systems.
- Industrial Motor Drives: Ensure uptime in high-vibration manufacturing setups.
