Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Infineon documentation. Confirm that the specific B5 suffix matches the required datasheet revision and technical specifications for your design. Ensure all handling and mounting procedures adhere strictly to the valid application notes provided by the manufacturer to maintain warranty coverage and operational safety.

Selection Notes

Select this module when designing systems requiring a 1200 V rating with high continuous current capabilities up to 580 A at lower case temperatures. Evaluate the thermal resistance values (0.062 K/W for IGBT, 0.11 K/W for diode) against your heatsink capacity. Consider the 20 nH stray inductance for switching speed optimization and ensure the operating junction temperature range of -40°C to 125°C aligns with your environmental constraints.
