Technical Specifications

Key Design Features

1. Press-Fit Technology:
• 5SDF1045H0002 uses press-fit pins instead of soldered connections, eliminating thermal fatigue and improving reliability in high-vibration environments (e.g., traction drives).
2. Dual-Channel Drive Architecture:
• 3BHL000986P3002 supports parallel IGBT operation with synchronized switching, enabling scalable power systems (e.g., 2,000A+ configurations via module paralleling).
3. Advanced Protection Circuitry:
• Desaturation detection (Vce monitoring) trips the IGBT within 1μs of overcurrent, preventing catastrophic failure.
• Integrated snubber capacitors (22nF/1.2kV) reduce voltage spikes during switching, extending module lifespan.
4. Thermal Management Integration:
• Module features an embedded NTC thermistor for real-time temperature monitoring, with the driver unit providing proportional cooling fan control (when paired with external fans).
