Understanding Gen4 SiC Schottky Technology 

The Gen4 1200V SiC Schottky series is built on advanced Junction Barrier Schottky (JBS) architecture, combining fast majority-carrier conduction with improved electric field control and leakage suppression. Unlike conventional silicon rectifiers, SiC Schottky devices eliminate minority carrier storage effects, resulting in negligible reverse recovery charge and significantly reduced switching losses.

Gen4 technology further enhances high-temperature stability and surge robustness, supporting operation from −55 °C to +175 °C with ultra-low leakage current and a positive temperature coefficient of forward voltage. This enables higher efficiency, improved thermal margins, and greater reliability in automotive, industrial, and renewable energy systems.
