Procurement Notes

Verify the specific ordering suffix BOSA1 against official Infineon documentation to confirm packaging and reel specifications. Ensure compatibility with required gate drive voltages and cooling fluid flow rates before procurement. Confirm RoHS compliance status and automotive qualification standards such as AQG 324 are met for the intended application environment.

Selection Notes

Select this module for high-power traction inverter designs requiring robust thermal management via direct liquid cooling. Evaluate the 750 V blocking capability against the system's DC link voltage, typically up to 450 V. Consider the 175 °C junction temperature capability for efficiency optimization and ensure the PCB mounting torque specifications are strictly followed to maintain mechanical integrity.

Part Context

This component belongs to the HybridPACK™ 2 family, which offers scalable power solutions for electric and hybrid vehicles. The series provides various current and voltage ratings within a standardized footprint, facilitating design flexibility across different vehicle platforms while maintaining consistent mechanical integration requirements for OEMs.

Replacement Considerations

Consult official Infineon cross-reference lists for verified substitutes. Direct replacements must match the HybridPACK™ 2 form factor, 750 V rating, and similar current capabilities. Verify that any alternative maintains compatible thermal resistance and pinout configurations.
