In motor control applications up to 2.5 kW, International Rectifier's 600V insulated gate bipolar transistors (IGBTs) reduce power dissipation in inverters by up to 60 percent or allow up to 60 percent higher rms current. The reduced power dissipation can reduce heatsink size by 50 percent. Each of the four new products in the family is co-packaged with an ultrafast soft recovery diode. The IRGB4062DPbF has typical reverse recovery energy of 621 µJ. The combination of low collector-to-emitter saturation voltage (VCE(ON)) (1.65V typical) and total switching energy (ETS) (ETS) of the trench IGBT results in reduced power dissipation and higher power density. The lead-free and RoHS-compliant IGBTs target motion control applications with wide switching frequency range such as in air conditioner and refrigerator compressors, washing machines, industrial drives, and circulating pumps.
