Low switching loss, 30A and 40A current ratings, and robust performance in a TO‑247AB package

MCC introduces the MIW30N65AT2Y and MIW40N65AT2Y, a new generation of 650V Trench and Field Stop (TFS) IGBTs designed to address the efficiency, thermal, and reliability challenges common in high‑power conversion systems. Housed in the industry‑standard TO‑247AB package, these Gen2 discrete IGBTs combine low switching loss with strong current handling to support compact, high‑density power designs. 

High switching losses and thermal constraints often limit system performance and long‑term reliability in industrial power applications. The MIW series uses advanced trench low‑loss technology to minimize switching and conduction losses while sustaining high power operation. With a maximum junction temperature of 175 °C, high ruggedness, and strong short‑circuit capability, these devices maintain stable operation under demanding electrical and thermal conditions. 

Available in 30A and 40A current ratings, the MIW30N65AT2Y and MIW40N65AT2Y give engineers flexible design options for scalable systems. A positive temperature coefficient further supports safe parallel operation, making the MIW series a practical solution for efficient, reliable, and robust industrial and power supply applications.
