High-efficiency switching with reduced spiking offered with wider package options

Nexperia has broadened the package options for its NextPower 80/100V MOSFETs portfolio now also includes LFPAK56 and LFPAK88 packaging. These devices have been developed to combine high efficiency with reduced spiking behaviour in telecommunications, server computing, industrial, power supply, fast charging, USB-PD, and motor control applications.

The Qg*RDSon FoM has long been a focus for semiconductor manufacturers aiming to improve the efficiency of MOSFET switches. However, relentlessly driving this figure ever lower has unintentionally increased spiking levels when a MOSFET switches on or off, raising the amount of generated EMI. Having identified this as an emerging issue, the company began to research how modifying other process technology parameters might assist in addressing it. These efforts culminated in it releasing its NextPower 80/100V MOSFETs with lower Qrr, allowing them to greatly lower the amount of spiking during switching transitions while displaying the same high-efficiency performance as competing MOSFETs but with lower EMI.

By making these high-efficiency, low-spiking MOSFETs available in LFPAK56 and LFPAK88, the company not only allows designers to decrease application size and benefit from the added robustness of copper clip packaging but also delivers new options to design engineers and customers looking to qualify further sources for existing designs.
