Power MOSFETs geared for hot-swap apps

NXP Semiconductors N.V. has introduced a family of linear mode Power MOSFETs engineered for 'hot-swap' environments. The NextPower Live family offers both excellent linear mode performance and a very low RDS(ON) value, boasted the company.

In order to cope with the in-rush current when a replacement board is plugged into a live system, MOSFETs need to have a strong linear mode performance and a wide safe operating area (SOA) to protect against power surges. However, this has traditionally required the use of older generation MOSFETs with poor RDS(ON) efficiency. The NXP NextPower Live family has overcome this problem, offering high linear mode performance to manage the power-up sequence while delivering very low levels of resistance once safely installed and in operation, NXP stated.

The NextPower Live portfolio incorporates 30V devices for applications such as blade servers operating on a 12VDC supply and 100V devices for telecommunications applications operating on a nominal 48VDC supply. Both voltage ranges come in D2PAK and LFPAK56 (Power-SO8 compatible) packages and are available now.
