We’re excited to introduce SwissSEM’s latest innovation: The i23 Series 900A/1200V Half-Bridge IGBT Modules, now in mass production.

Engineered for high efficiency and reliability, these modules are ideal for demanding applications in renewable energy, industrial automation, and electric mobility. The i23 Series minimizes saturation voltage and switching losses—delivering higher performance where it matters most.

Key Technical Highlights

Ultra-low V_CE(sat): Just 1.55V at 900A (25°C)
Optimized FRD: 0.25V lower V_F for energy storage PCS
d23 Diode: Soft recovery design for safe reverse recovery—perfect for 3-level energy storage
Advanced thermal management: High-performance insulated substrates for superior heat dissipation
Industry-standard packaging: With low internal impedance for high current density
Rated up to 175°C junction temperature for long-term durability

Why Choose i23

Proprietary IGBT and diode chips developed in-house
Custom packaging for high-current (900A) modules with copper wire bonding and large area power terminals
Tight parameter distribution supports direct parallel operation—no matching needed
Built for harsh conditions: High resistance to moisture and salt spray environments
Backed by full manufacturing, quality, and supply-chain support

Application Areas

1500V centralized photovoltaic (PV) inverters
Centralized energy storage converters
Electric drive systems for commercial vehicle drives
Variable frequency drives (VFDs) and inverter-based welders
UPS systems and auxiliary traction power supplies
Frequency converters

Now available in 450A–900A current ratings
