Nexperia has introduced new 0.55 mΩ RDS(on), 40-V power mosfets in the high-reliability LFPAK88 package for automotive (BUK7S0R5-40H) and industrial (PSMNR55-40SSH) applications. These devices are the lowest RDS(on) 40-V parts that Nexperia has produced.
Nexperia claims these devices offer power densities more than 50× greater than traditional D2PAK devices as well as improved performance in both Avalanche and Linear mode for higher reliability and increased ruggedness. The company attributes the performance increases to a combination of the latest high performance superjunction silicon technology with its LFPAK copper clip technology, which enables them to use more silicon in the package.
Nexperia said these figures are 1.5 – 2× better than the competition and offer the best single pulse avalanche rating (EAS) at 2.3 J and very strong ID current rating of 500 A, which is a measured rather than theoretical limit.
Together, these performance and size advantages enable designers to replace two paralleled old-style components with one new LFPAK88. The AEC-Q101-qualified BUK7S0R5-40H parts target automotive applications including braking, power steering, reverse battery protection, e-fuse, DC/DC converter, and motor control applications. The industrial PSMNR55-40SSH MOSFETs suit battery isolation, current limitation, e-fuse, motor control, synchronous rectification and load switch applications in power tools, appliances, fans; and e-bikes, scooters and wheelchairs.
