Electromagnetic Compatibility

Adrian Stirn / Editor: Gerhard Stelzer, Würth Elektronik eiSos

With just one twisted pair of wires, Single-Pair Ethernet is a convincingly lean solution. This cabling becomes even more efficient if it is also used for power supply in addition to data transmission - this is referred to as "Single-Pair with Power-over-Ethernet" (SPoE). What about electromagnetic compatibili

Next-generation SJ MOSFETs extend performance of silicon-based power devices

Franz Stückler, Infineon Technologies

For more than a decade, development of Infineon's CoolMOS™ super-junction (SJ) MOSFET technology has extended the "silicon limit line" that restricts the performance of planar-type power MOSFETs.
