MIW40N65AH2Y 650V Trench Field-Stop IGBT Featuring Low VCE(sat), Low Switching Loss, and Reliable Thermal Performance in a TO-247AB Package

Micro Commercial Components (MCC) introduces the MIW40N65AH2Y, a high-performance 650V Trench Field-Stop IGBT designed to improve efficiency, thermal performance, and reliability in demanding industrial power conversion systems. As modern power electronics continue to increase switching frequencies and power density, engineers require IGBT solutions that reduce switching losses while maintaining excellent thermal stability under heavy operating conditions.

The MIW40N65AH2Y addresses these challenges by combining a 650V collector-emitter voltage rating with a 40A continuous collector current in the industry-standard TO-247AB package. Built on advanced Trench Field-Stop technology, the device features a low collector-emitter saturation voltage (VCE(sat)) of only 2.2V, smooth switching performance, a positive temperature coefficient for simplified parallel operation, and a maximum junction temperature of 175°C. These characteristics make it well suited for industrial power supplies, motor drives, renewable energy systems, uninterruptible power supplies (UPS), welding equipment, and high-power switching applications.
