Low RDS(on) 40 V MOSFETs from Nexperia deliver highest power density for Automotive and Industrial applications

Class-leading SOA and Avalanche characteristics increase ruggedness and reliability

Nijmegen, May 27 2021: Nexperia, the expert in essential semiconductors, today announced 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 ever produced and more importantly, they deliver power densities more than 50X greater than traditional D2PAK devices. More, the new devices also offer improved performance in both Avalanche and Linear mode, leading to increased ruggedness and reliability.

Neil Massey, Nexperia’s Product Marketing Manager comments: “The new 8 x 8 mm LFPAK88 MOSFETs combine the latest high performance superjunction silicon technology with our proven LFPAK copper clip technology, which is renowned for delivering significant electrical and thermal performance benefits. The resulting low RDS(on) enables us to pack more silicon in the package, improving power density and shrinking device footprint.”

Measuring just 8 x 8 x 1.7 mm, the new power MOSFETs also feature class-leading linear mode / safe operating area (SOA) characteristics for safe and reliable switching at high current conditions. SOA at 1 ms, 20 VDS operating conditions is 35 A due to a combination of silicon and package, while at 10 ms, 20 VDS where the package dominates, SOA is 17 A. These figures are 1.5 – 2x better than the competition. The devices also offer the best single pulse avalanche rating (EAS) at 2.3 J and very strong ID current rating of 500 A, which – unlike some competing devices – is a measured rather than theoretical limit.

The size and performance benefits afforded by the Nexperia 8 x 8 mm LFPAK88 MOSFETs enable designers to replace two paralleled old-style components with one new LFPAK88, simplifying manufacturing and increasing reliability. The AEC-Q101-qualified BUK7S0R5-40H parts – which deliver more than twice the reliability performance demanded by the automotive standard – suit 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.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
