GenevaSTMicroelectronics has introduced IGBTs that use innovative and efficient lifetime-control techniques to reduce energy loss during turn off.
New devices, including the STGxL6NC60D 600V PowerMESH IGBT, allow designers to use low-cost IGBT technology in energy-sensitive circuits such as lighting ballasts operating well above 20kHz, achieving greater overall efficiency than standard-technology MOSFETs, according to ST.
The improvements in switching performance also allow designers to use IGBTs highly competitive designs with hard-switching topologies as well as with resonant circuits. In addition, the lower turn-off energy allows the device to operate at low junction temperature with a small snubber capacitor, leading to greater benefits including reduced power dissipation, greater reliability and a smaller footprint.
Applications include high-frequency lighting ballasts from 70W to 150W, as well as switched-mode power supplies, power-factor controllers and other high-frequency power-switching applications.
The four devices that make up the STGxL6NC60D series provide a choice of power packages, with TO-220, TO-220FP, DPAK and D2PAK options.
Pricing: Starts at $0.35 for the STGPL6NC60D in the TO-220 package, for orders more than five million pieces.
