To ensure genuine procurement, stable inventory, and professional technical support, ROHM partners with top-tier authorized distributors worldwide, enabling seamless access to these mission-critical components for manufacturers and designers.
Core Product Lines & Technical Advantages
ROHM’s IGBTs cover three key segments, each optimized for specific high-voltage scenarios with advanced technological features derived from rigorous semiconductor design:
1. 4th Generation Automotive-Grade IGBTs (AEC-Q101 Qualified)
Engineered for harsh automotive environments, these 1200V IGBTs set benchmarks in low-loss performance and short-circuit resilience, ideal for electric compressors and HV heaters:
RGA80TRX2HR/RGA80TRX2EHR: Flagship 1200V/80A automotive IGBTs with AEC-Q101 certification and 10μs short-circuit withstand time (Tj=25℃) – an industry-leading specification for fault protection. Available in TO-247-N and 4-terminal TO-247-4L packages, the latter features a Kelvin emitter terminal for high-speed switching and enhanced creepage distance (supporting 1100V in pollution degree 2 environments), reducing design burden for manufacturers <superscript:1superscript:6. When applied in 3-phase inverters, these models cut losses by 24% vs. standard products and 35% vs. conventional alternatives.
Bare Chip Variants (SG84xxWN Series): Complementary 11-model bare chip lineup for custom module integration, extending the 4th Gen technology to high-power automotive systems like EV inverters, with plans for further lineup expansion <superscript:1.
2. Industrial-Grade Field Stop Trench IGBTs
Optimized for industrial power conversion, these 650V-1200V devices combine fast switching, low saturation voltage, and cost-effectiveness for inverters, UPS, and induction heating equipment:
RGW Series (High-Speed Switching): 650V IGBTs (e.g., RGWS80TS65D) with built-in fast recovery diode (FRD), low VCE(sat)=1.5V typ., and switching loss reduction via refined EM cell design. Ideal for air conditioners, industrial inverters, and power conditioners, with soft switching characteristics that cut voltage overshoot by up to 50% vs. conventional models <superscript:2superscript:4.
RGCL Series (Low VCE(sat)): 600V IGBTs (e.g., RGCL80TS60) focused on conduction loss minimization, with VCE(sat) as low as 1.2V. Suitable for high-efficiency industrial power supplies and welding machines, balancing low loss and thermal stability.
3. Short-Circuit Tolerant IGBTs (RGT Series)
Designed for rugged industrial applications requiring fault resilience, these devices integrate short-circuit protection and built-in FRDs:
RGT30NS65D: 650V/15A IGBT with 5μs short-circuit withstand time, built-in ultra-fast recovery FRD, and TO-262 package. Features low switching loss (Tf=75ns typ.) and RoHS compliance, ideal for small industrial inverters and consumer electronics like induction cookers <superscript:7.
RGTv Series (2μs Short-Circuit Tolerance): 650V models (e.g., RGTv60TS65) with extreme fault resilience, targeting high-reliability industrial systems where short-circuit events demand rapid interruption <superscript:4.
Key Technological Advantages
Proprietary Field Stop Trench Structure: Combines thin-wafer technology (15% reduced wafer thickness vs. conventional) with optimized cell design, achieving low VCE(sat) and switching loss for enhanced energy efficiency <superscript:4.
Automotive Functional Safety Compliance: Developed under ISO 26262-certified processes, with over 1,000 product variants supporting ASIL-level safety requirements for automotive systems <superscript:3.
