The ABB 5SHY35L4520 is an asymmetric IGCT module with a rated voltage of 4500 V and current of 4000 A (RMS), optimized for medium-frequency operations. Its press-pack design and planar technology ensure low thermal resistance (0.01 K/W) and robust surge current capability (50 kA, 10 ms). Key features include snubberless turn-off capability, high electromagnetic immunity, and a simple control interface with status feedback. Compatible with AC/DC supply voltages, the module supports series connection for scalable power systems. Built for harsh environments (-40°C to +125°C), it integrates advanced fault protection and diagnostic functions.
Snubberless Operation: Eliminates external snubber circuits, reducing system complexity and cost.
Medium-Frequency Optimization: Ideal for 50–1000 Hz applications, enhancing efficiency in industrial drives.
High Power Density: 4000 A RMS in a compact design (15% higher current density than previous models).
Reliability: MTBF > 100,000 hours (ABB testing), with resistance to thermal cycling and vibration.
Diagnostic Integration: Real-time status feedback for predictive maintenance.
4. Application Areas and Cases
Industries: Metals (aluminum smelting), energy (HVDC converters), transportation (rail traction), and industrial machinery. Case Study: A European paper mill reduced energy losses by 12% using the 5SHY35L4520 in its induction motor drive system. The module’s snubberless design and low voltage drop improved system efficiency, while its rugged construction minimized downtime in humid environments.
5. Competitor Comparison
Compared to similar IGCT modules:
Higher Current Rating: 4000 A RMS (vs. typical 3500 A in 竞品).
Lower Thermal Resistance: 0.01 K/W (10% better than market averages).
Integrated Diagnostics: Built-in status feedback (standard vs. optional in 竞品).

6. Selection Recommendations
Power Requirements: Suitable for systems requiring 3500–4500 A RMS and 4000+ V.
Cooling Systems: Pair with ABB liquid-cooled heat sinks for continuous high-duty cycles.
Environment: IP65 enclosures recommended for outdoor/harsh environments.
Scalability: Series connection capability for voltage-doubling in HVDC applications.
7. Precautions
Installation: Torque mounting bolts to 25–30 N·m (verify with ABB torque guidelines).
Cooling: Maintain heat sink temperature <85°C (liquid cooling mandatory for full load).
Voltage Spikes: Use surge protection devices (SPDs) for transient voltage suppression.
Maintenance: Inspect contact pressure annually; replace every 15 years (expected lifecycle).
