Power MOSFETs tackle eco-design stds

The industry’s first super-junction transistors capable of withstanding peak voltages up to 950 V with the STx20N95K5 and STx6N95K5 MOSFETs, as well as the STx21N90K5, a 900V device offering best-in-class energy efficiency, and the STL23N85K5, the world’s only 850V device offered in the PowerFLAT 8 x 8-mm HV package. Applications include flat-panel televisions, PC power supplies, LED lighting drivers, and electronic ballasts for High-Intensity Discharge (HID) lamps.

The 900–V STP21N90K5 figure of merit is 62.5% better than the only comparable alternative device in the market. The high voltage rating of the MOSFETs increase system safety and reliability. (From $3.50 to $10.00 ea/1,000 — available now.)
