IGBT and Rectifier Diode Modules come in diverse package designs.

May 23, 2014

Intended for power control applications, Half-Bridge Circuit IGBT Modules come in S, D, or WD packages with ratings up to 1,200 V and 600 A. Minimized loss promotes efficiency and switching speed, while short circuit capability reduces protection requirements. With ratings up to 1,800 V and 200 A, Phase Leg and Common Cathode Circuit Rectifier Diode Modules come in S and A packages. Reverse recovery loss promotes operational efficiency, and forward voltage allows for reduced heat dissipation. Read More
