Infineon – Silicon Carbide CoolSiC™ Schottky Diode solutions – Improve efficiency and solution costs
Infineon is the world’s first Silicon Carbide (SiC) discrete power supplier. Long market presence and experience enable Infineon to deliver highly reliable, industry-leading SiC performance. The differences in material properties between Silicon Carbide and Silicon limit the fabrication of practical Silicon unipolar diodes (Schottky diodes) to a range up to 100 V–150 V, with relatively high on-state resistance and leakage current. In SiC material Schottky diodes can reach a much higher breakdown voltage. The Infineon portfolio of Silicon Carbide (SiC) products covers 600 V and 650 V to 1200 V Schottky diodes.
