FF450R12KT4 Core Features: Built for High Performance

4th Generation IGBT4 Technology – Comprehensive Performance Upgrade

The FF450R12KT4 utilizes Infineon’s 4th generation high-speed trench gate/field stop IGBT4 technology, paired with optimized emitter-controlled HE diodes. Compared to previous generations, this technology achieves an excellent balance between conduction loss and switching loss, reducing dynamic losses by about 15%, making it especially suitable for frequent start-stop operations.

Excellent Electrical Performance

Thanks to IGBT4 technology, the FF450R12KT4 strikes an outstanding balance between switching speed and saturation voltage. At a switching frequency of 4kHz, overall system efficiency can reach 98.7%, which is 1.2 percentage points higher than the industry average. The positive temperature coefficient ensures automatic current sharing when modules are paralleled, eliminating the need for additional current balancing measures and significantly simplifying system design for multi-module parallel configurations.

Superior Thermal Management

The module features a copper baseplate plus low thermal resistance Al₂O₃ substrate design, with a junction-to-case thermal resistance as low as 0.062K/W. Combined with an optimized 0.8mm baseplate structure, thermal resistance is 22% lower than similar products, significantly improving heat dissipation efficiency and system reliability.
