Key Features
High Integration & Snubber-less
Chip, diode, drive and protection are fully integrated. No additional snubber circuits required, reducing component count and improving system reliability and power density.
Fast Turn-off & Voltage Balancing Advantage
Short and consistent turn-off time ensures uniform dynamic voltage distribution in series, reduces overvoltage risk, and fits high-voltage series topologies.
Low Loss & High Efficiency
Low on-state voltage and low switching loss, system efficiency over 98%, ideal for high-power continuous operation.
Hardware Fault Tolerance & Long Lifetime
Adopts TMR (Triple Modular Redundancy) architecture with microsecond fault response; reduces voltage stress on single device, lifetime ~20 times longer than conventional solutions.
Press-Pack & Easy Maintenance
Disc structure optimizes heat dissipation; modular design enables easy replacement and lowers maintenance cost.
