HybridPACK™ Drive IGBT Module – Automotive Traction Inverter Power Module (30kW-250kW)
HybridPACK™ is a compact, scalable automotive power module specifically designed for main traction inverters in hybrid and electric vehicles (xEV), covering a power range of 30kW to 250kW. Compliant with AQG 324 and AEC-Q101 standards, it integrates Trench/Fieldstop IGBT3/4 chips featuring low saturation voltage (Vce(sat)) and high mechanical robustness. Key benefits include minimized power losses, enhanced thermal cycling capability, and simplified assembly via PressFIT signal pins. Optimized for 750V/1200V bus voltages with low stray inductance (8nH typical) and advanced direct water cooling (PinFin/Wave), it enables cost-effective, high-reliability inverter designs for mass production xEV platforms.
Key Technical Highlights
- Automotive-Grade Reliability: Fully qualified to AQG 324 and AEC-Q101, passing rigorous automotive stress tests including temperature cycling, power cycling, humidity and vibration tests, ensuring stable performance throughout the vehicle's lifetime.
- High-Efficiency Chip Technology: Adopting Trench/Fieldstop IGBT3 and IGBT4 chips, the module achieves extremely low saturation voltage, significantly reducing conduction losses. Combined with optimized switching characteristics, it improves inverter efficiency and helps extend the driving range of electric vehicles.
- Superior Mechanical Robustness: The package design delivers high mechanical strength, with excellent resistance to vibration, shock and thermal stress. PressFIT signal pins eliminate selective soldering, improving assembly efficiency and long-term reliability while reducing production costs.
- Optimized Thermal & Power Density: Equipped with PinFin and Wave direct water cooling structures, the module achieves low thermal resistance and efficient heat dissipation. The compact package design increases power density, enabling smaller and lighter inverter systems.
- Low Stray Inductance Design: The internal layout is optimized to reduce stray inductance to a typical 8nH, effectively suppressing voltage spikes during switching. This improves system stability, allows higher switching frequencies and enhances the overall safety of the inverter.

Frequently Asked Questions
Q1: What's the difference between CoolSiC™ G1 and G2 in HybridPACK™ Drive series? Which one is more cost-effective for mass production?
A1: G1 is 1st-generation SiC, mature and more cost-effective; G2 is upgraded technology with lower loss and higher power density. For mid-range EVs in mass production, G1 offers better cost-effectiveness; for high-end/high-power models, G2 provides long-term energy savings benefits.
Q2: Can HybridPACK™ models with PinFin cooling be replaced with Wave cooling directly?
A2: No. PinFin and Wave cooling systems have different substrate designs; direct replacement will cause poor heat dissipation, potentially leading to module damage. Always choose the same cooling type as specified in your original design.
Q3: Why do some models have long/short busbars? How to choose for my EV assembly line?
A3: Long busbars are designed for large-space installations (e.g., commercial vehicles); short busbars are optimized for compact layouts (e.g., passenger cars). Select based on your inverter's internal space constraints and wiring distance requirements.
Q4: Do all overseas models support global after-sales service? How long is the general lead time?
A4: Yes, all models support global after-sales service. Lead times typically range from 1-2 weeks for regular models to 2-4 weeks for new or rare models (e.g., FS01MR08A8MA2C).
Q5: Will HybridPACK™ work normally in high-temperature areas (e.g., Middle East) or cold areas (e.g., Northern Europe)?
A5: Yes. All models are designed to operate within -40°C to 150°C temperature ranges; no additional modifications are needed. Ensure your inverter's cooling/heating system functions properly in extreme environments.
Q6: Can I use 750V models for 1200V EV systems? What's the risk?
A6: No. 750V models cannot withstand 1200V operating voltages; this will cause insulation breakdown and module burnout. Always match the voltage class precisely with your EV's bus voltage requirements.
Q7: What's the common failure of HybridPACK™ in actual use? How to avoid it?
A7: The most common failure is overheating due to inadequate cooling. Prevent this by regularly cleaning the cooling system and ensuring water channels remain unobstructed (for water-cooled models).
Q8: Do I need special tools to assemble PressFIT pin models? Can ordinary assembly tools be used?
A8: Yes, specialized PressFIT tools are required. Ordinary tools may damage the pins, leading to poor electrical contact. Always use Infineon-recommended PressFIT assembly tools for proper installation.
