New Product Release | i23 Series Micro-Pattern Trench IGBT Chips

Date: 2025-07-10

The i23 series chip set adopts advanced micro-pattern trench IGBT technology, delivering lower saturation voltage (V<sub>CE(sat)</sub>), higher current density, and reduced switching losses. These chips meet the industry's highest standards for reliability. The d23 series chips feature lower forward voltage drop and reduced reverse recovery losses. When used in combination, the i23 and d23 chips significantly enhance module performance while ensuring long-term reliability.
