Description
1. Product Description
The 5SHY3545L0005 (4500 V/3500 A RMS) and 5SHY3545L0009 (4500 V/4500 A RMS) are asymmetric IGCTs optimized for medium-frequency (50–1000 Hz) operations. Their press-pack architecture ensures low thermal resistance (0.012 K/W for 0005; 0.01 K/W for 0009) and surge current capability (45 kA for 0005; 55 kA for 0009, 10 ms). Both models feature snubberless turn-off, high di/dt and dv/dt ratings, and integrated diagnostic functions for real-time status monitoring. Compatible with liquid-cooled systems, they support series/parallel configurations for scalable voltage/current requirements.

3. Advantages and Features
- Snubberless Design: Eliminates external components, reducing system complexity (50% fewer parts vs. traditional thyristors).
- High Power Density: 4500 A RMS (0009) – 28% higher than legacy models.
- Reliability: MTBF > 120,000 hours (ABB testing), with resistance to thermal cycling (100,000 cycles at ΔT=80K).
- Diagnostic Integration: Built-in voltage/current sensors for predictive maintenance.
- Efficiency: Low forward voltage drop (1.5 V at full load) reduces power losses by 10% vs. competitors.
4. Application Areas and Cases
Industries: HVDC transmission, rail traction, aluminum smelting, and renewable energy (wind/solar inverters).

6. Selection Recommendations
- Current Needs: Choose 5SHY3545L0005 for 3000–3800 A systems; 0009 for 4000–4800 A.
- Cooling: Pair with ABB ALSTOM liquid-cooled heat sinks (e.g., HSK1200) for continuous operation.
- Voltage Scaling: Series connection supports up to 18 kV (4 modules) for HVDC applications.
- Environment: IP65 enclosures recommended for outdoor use (salt mist/dust resistance).
7. Precautions
-
Mounting: Apply 40 kN uniform pressure (torque: 25–30 N·m for M10 bolts).
-
Cooling: Maintain heat sink temperature <85°C (liquid cooling mandatory for >70% load).
-
Surge Protection: Use ABB MOV surge arresters (e.g., OVR120) for transient voltage spikes.
-
Maintenance: Inspect contact pressure annually; replace every 12–15 years (depending on duty cycle).
