Description

The IXYF40N450 is a high-voltage IGBT transistor designed for demanding power switching applications. With a collector-emitter breakdown voltage of 4500V and a continuous collector current rating of 32A at 110°C, the IXYF40N450 offers strong performance in industrial and energy systems. This device combines Littelfuse’s advanced XPT technology with an ISOPLUS i4-Pak package that provides electrical isolation and simplified mounting. By using the IXYF40N450, designers benefit from high power density, reduced gate drive requirements, and reliable operation in switch-mode power supplies, UPS systems, laser generators, and capacitor discharge circuits. Its low saturation voltage and high peak current capability make the IXYF40N450 suitable for efficient energy transfer and robust thermal performance in high-stress environments.
