Extended Temperature Mid-Voltage MOSFETs Rated at 175° C

Extended Temperature Mid-Voltage MOSFETs Rated at 175° C

Fairchild is enabling manufacturers to im-prove the reliability and performance of their products with its expanded line of extended temperature (ET) mid-voltage MOSFETs, which can operate at 175° C. The higher op-erating temperatures enable up to 85 percent greater power density and three times more reliability than MOSFETs rated to the 150° C industry standard.

This family of ET MOSFETs aligns with the IPC-9592 power conversion standard, which means the maximum junction temperature can be up to 150° C, as opposed to 125° C for standard 150° C MOSFETs, to enable more design margin. The family includes 19 new devices, available in both 5mm x 6mm and 3mm x 3mm standard packages, as well as the new TOLeadless (TO-LL) package. The devices are offered in a wide range of voltage rat-ings, including 30V, 40V, 60V, 80V, 100V, 120V and 150V. Their outstanding com-bination of superior heat tolerance, greater power density and improved reliability make Fairchild’s ET MOSFET family ideal for DC-to-DC power supplies, AC-to-DC power supplies and motor drives used in a variety of applications, including avionics, micro solar inverters, power tools and tele-communications.
