Nexperia MOSFETs deliver best-in-class safe operating area and improved RDS(on) for hot swap designs

Nexperia, theglobal leader in discretes, logic and MOSFET devices, has introducedthe latest addition to its NextPower Live linear-mode MOSFET family, PSMN3R7-100BSE delivers a best-in-class combination of strong Safe Operating Area (SOA) and low RDS(on), and is ideally suitedfor hot swap, soft start and e-fuse applications. In order to manage the high in-rush current that can occur when swapping a server board or other pluggable system, or to ensure that a processor board is brought up smoothly, a MOSFET with high SOA is used in conjunction with a hot swap controller. Previous generation parts have traded off SOA against RDS(on), whereas the new technology maximises SOA without affecting RDS(on), thereby maintaining high operating efficiency levels.

Nexperia’s new PSMN3R7-100BSE MOSFETs improve SOA with a four-fold improvement in linear mode performance compared to standard technology, yet have a maximum RDS(on) of only 3.95 mΩ (3.36 mΩ typ.) – around 18 per cent less than previous devices. These N-channel 100V devices are available in the D2PAK package, qualified to 175°C. Devices are fully compatible with hot-swap controllers fromall leading manufacturers

Mike Becker, Nexperia’s product manager said: “Server and communications infrastructure companies are packing more and more processing power onto their blades and rack-based systems, continually pushing up power requirements. Reliable hot-swap operation is essential to manage the in-rush currents experienced during start-up, but as power levels rise and efficiency requirements increase, then low RDS(on) is also becoming more important. NextPower Live MOSFETs from Nexperia, deliver benchmark combination of strong SOA and low RDS(on), allowing engineers to design ultra-rugged hot-swap solutions to manage the in-rush currents, whilst lower RDS(on) delivers the highest level of efficiency.”
