600-V MOSFETs improve efficiency, shrink footprint

The TK31N60X, TK39N60X and TK62N60X series of high-speed switching type super junction MOSFETs are fourth generation 600-V super junction MOSFET DTMOS IV devices. They suit applications that require high reliability, power efficiency and a compact design, such as high efficiency switching power supplies for servers and telecom base stations; and as power conditioners for photovoltaic inverters.

The MOSFETs achieve a high speed switching performance while keeping the low on-resistance level of conventional DTMOS IV without loss of power. This is accomplished through the 45% reduction of parasitic capacitance between gate and drain. The RDSon at 10-V is as low as 0.040 Ω.
