Nexperia Expands Package Options for NextPower 80/100 V MOSFETs, Offering Enhanced Efficiency and Reduced EMI

Category articles

Nexperia, an internationally acclaimed expert in semiconductor technology, today made an exciting announcement: they have expanded the package options available for their NextPower 80/100 V MOSFETs portfolio from LFPAK56E to include LFPAK56 and LFPAK88 for greater design flexibility and engineering convenience. These advanced devices are engineered specifically to offer maximum efficiency while minimising any potential spiking behaviour, making them suitable for applications including telecom, server computing, industrial systems power supply units fast charging solutions USB-PD devices motor control systems and motor control systems among many other uses.

At Nexperia, the Qg*RDSon figure of merit has long been at the core of their efforts to enhance MOSFET switch efficiency. Yet in their pursuit to reduce it further, semiconductor manufacturers have unfortunately unintentionally caused increased spiking levels during switching operations and increased electromagnetic interference (EMI). Recognizing this emerging issue, Nexperia undertook extensive research efforts in search of alternative process technology parameters which may effectively address it.

Nexperia’s hard work paid off with the launch of NextPower 80/100 V MOSFETs featuring reduced Qrr (reverse recovery charge), marking an important advancement that allows significant reduction of switching transition spikes while maintaining similar high efficiency performance while producing reduced electromagnetic interference levels compared to their competition. This feat of design represents a true achievement that ensures optimal performance and reliability across various applications.

Nexperia’s expansion of their high-efficiency, low-spiking NextPower 80/100 V MOSFETs into LFPAK56 and LFPAK88 packages gives designers more power to reduce application size while taking advantage of copper clip packaging durability for added reliability and flexibility. Furthermore, this growth opens new avenues for design engineers and customers seeking additional sources for existing designs that provide greater flexibility and reliability.

Nexperia continues to demonstrate its dedication to semiconductor technology by producing more efficient and reliable electronic systems across a wide variety of industries. Their expanded NextPower MOSFETs portfolio is testament to this dedication as it serves the ever-evolving needs of designers, engineers and customers alike.

Spiking Behavior in Telecommunications

Spiking behavior refers to any unexpected voltage spikes or transients during switching of electronic components like MOSFETs that cause fluctuations or disturbances to electrical signals, leading to potential interference or disruption with telecommunication systems. Causes for such behavior could include component characteristics and circuit design features – thus making its prevention essential in maintaining efficient communications operations.

Qrr Reverse Recovery Charge

Reverse Recovery Capacitance of Diodes It is a parameter that describes the amount of charge stored in a diode’s junction capacitance during its reverse recovery process. When switching from conducting state to non-conducting state, charge carriers need time to leave and the diode regain its non-conductive state; this time period is known as Reverse Recovery.

Qrr represents the total charge to be dissipated during recovery period. It’s an essential consideration in applications requiring fast switching or high-frequency operation; lower Qrr values indicate faster diode recovery which leads to reduced power losses, improved switching performance and less electromagnetic interference (EMI) generation.

Nexperia’s NextPower 80/100 V MOSFETs feature lower Qrr values than competing MOSFETs, meaning they exhibit reduced spiking behavior during switching transitions and produce less EMI compared to them. This enhancement results in better overall performance and reliability across various applications including telecom, server computing, industrial power supply fast charging USB-PD motor control systems and motor control applications.
