Professional magazine and portal dedicated to electronics Low Rds(on) 40 V MOSFETs from Nexperia deliver highest power density for Automotive and Industrial applications
Nexperia 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.
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 (more info).
