Mitsubishi S1 1.7kV HVIGBT Module Low Loss IPM Power Module For Rail

Mitsubishi S1-Series 1.7kV HVIGBT Module | Low Loss High Reliability for Rail

S1-Series 1.7kV HVIGBT Module

Low Loss High Reliability for Rail Applications

S1-Series 1.7kV HVIGBT modules with RFC Diode & CSTBT chip deliver 2.2x higher RRSOA and low thermal resistance. Engineered for railway traction and HVDC transmission applications, these modules offer easy replacement capabilities.

Core Technical Highlights

2.2x Enhanced Switching Reliability: Proprietary RFC diode boosts RRSOA withstand capacity, eliminating reverse recovery failure during switching operations.
6.0kVrms Reinforced Insulation: 1.5x higher than previous models, prevents insulation failure and short circuits in high-voltage scenarios, supporting multi-topology inverters.
Low Loss & Thermal Resistance: RFC diode + CSTBT chip synergy reduces power loss, minimizes heat generation, and eases thermal management burden.
1.7kV Custom High-Voltage Rating: Tailored for rail traction inverters and HVDC converter valves, ideal for high-voltage/high-power industrial power conversion.
Seamless Drop-In Replacement: Identical external dimensions to existing modules, eliminating installation redesign requirements and reducing retrofit costs and design cycles.
Long-Term Operational Stability: High-reliability core components combined with robust structural design reduce failure and downtime risks while lowering maintenance frequency and O&M costs.
Harsh Condition Adaptability: Optimized structure and materials ensure consistent performance in demanding rail and power infrastructure operating environments.
