Infineon launches first 2000V SiC Schottky diode
Many industrial applications are transitioning to higher power levels with minimized power losses, which can be achieved through increased DC link voltage. Infineon Technologies AG of Munich, Germany has hence addressed this challenge by introducing the CoolSiC Schottky diode 2000V G5, which is claimed to be the first discrete silicon carbide diode on the market with a breakdown voltage of 2000V. The product family is suitable for applications with DC link voltages up to 1500VDC and offers current ratings from 10A to 80A, making it suitable for higher DC link voltage applications such as in solar and electric vehicle (EV) charging applications.
The product family comes in a TO-247PLUS-4-HCC package, with 14mm creepage and 5.4mm clearance distance. This, together with a current rating of up to 80A, enables a significantly higher power density. It allows developers to achieve higher power levels in their applications with only half the component count of 1200V solutions, simplifying the overall design and enabling a smooth transition from multi-level topologies to 2-level topologies.

In addition, the CoolSiC Schottky diode 2000V G5 utilizes .XT interconnection technology, which leads to significantly lower thermal resistance and impedance, enabling better heat management. Furthermore, the robustness against humidity has been demonstrated in HV-H3TRB reliability tests. The diodes exhibit neither reverse recovery current nor forward recovery and feature a low forward voltage, ensuring enhanced system performance.
The 2000V diode family is a match for the CoolSiC MOSFETs 2000V in the TO-247Plus-4 HCC package that Infineon introduced in spring 2024. The CoolSiC diodes 2000V portfolio will be extended by offering them in the TO-247-2 package, which will be available in December. A matching gate driver portfolio is also available for the CoolSiC MOSFETs 2000V.
The CoolSiC Schottky diode 2000V G5 family in TO-247PLUS-4 HCC is available now. An evaluation board for product family is also available.
