IR Expands Family of IGBTs with 600V Trench Ultrafast IRGR4045DPBF and IRGS4045DPBF for Appliance Motor Drives

EL SEGUNDO, Calif. - International Rectifier, IR (NYSE: IRF) today announced the expansion of its family of Insulated Gate Bipolar Transistors (IGBTs) with the introduction of the IRGR4045DPbF and IRGS4045DPbF. The new 600V Trench ultrafast IGBTs offer improved performance and higher efficiency for appliance and light industrial motor drive applications including washers and refrigerators.

The IRGR4045DPbF and IRGS4045DPbF utilize IRs thin wafer Field-Stop Trench technology that significantly reduces switching and conduction losses to deliver higher power density and greater efficiency at higher frequencies. Co-packaged with a diode and available in DPAK and D2Pak packages, the new IGBTs feature a nominal current of 6A and a minimum short circuit rating of ≥ 5s.

The new devices also offer low VCE(on) to reduce power dissipation and achieve higher power density, and positive VCE(on) temperature coefficient for easy paralleling. The IRGR4045DPbF and IRGS4045DPbF are suitable for a wide range of switching frequencies, optimized up to 20kHz.

The IRGR4045DPbF and IRGS4045DPbF expand IRs extensive portfolio of IGBTs and offer a highly efficient and reliable solution for high performance appliance and light industrial applications, said Llewellyn Vaughan-Edmunds, IGBT Product Marketing Manager, IRs Energy Saving Products Business Unit.

Offered as both die and packaged devices other key features of the IRGR4045DPbF and IRGS4045DPbF include optimized square reverse bias safe operating area (RBSOA), maximum junction temperature of 175 C and low EMI for improved reliability.
