Semiconductor specialist Nexperia is expanding its packaging options for its portfolio of NextPower 80/100 V MOSFETs, previously only available in LFPAK56E. Options now include LFPAK56 and LFPAK88 packaging.
These devices are designed to combine high efficiency with reduced spike behavior in telecommunications, server computing, industrial, power supply, fast charging, USB-PD, and motor control applications.
The Qg*RDSon figure of merit has been a focus for semiconductor manufacturers looking to improve the efficiency of MOSFET switches.
However, relentlessly pushing this number down has had the unintended consequence of increasing peak levels when a MOSFET is turned on or off, increasing the amount of electromagnetic interference (EMI) generated.
Having identified this issue as emerging, Nexperia began researching how modifying other process technology parameters could help resolve it. These efforts have resulted in the company's NextPower 80/100V MOSFETs with lower Qrr (reverse recovery charge), allowing them to significantly reduce the amount of spikes during switching transitions while still exhibiting the same high-efficiency performance as Competing MOSFETs – but with lower EMI. .
By making these high-efficiency, low-peak NextPower 80/100V MOSFETs available in LFPAK56 and LFPAK88, Nexperia not only allows designers to downsize their application and benefit from the copper clip package, but also provides new options for engineers projects and clients looking to qualify additional sources for their existing projects.
