New LFPAK56 MOSFETs from Nexperia feature improved creepage and clearance, meeting UL2595


Industry’s only available devices compatible with Power-SO8 footprint to meet new standard for battery-powered equipment

Nexperia, today announced that two of its LFPAK56-packaged portfolio of MOSFETs are now available with improved creepage and clearance to meet UL2595 requirements for battery-powered equipment rated between 15 and 32 V. Devices are 100% compatible with the industry-standard Power-SO8 footprint; no other compact, surface-mount devices yet meet UL2595 which calls for minimum creepage and clearance distances of 1.5mm between Source and Drain terminals.


Unlike some competing Power-SO8 types which are constructed using wire bonding, Nexperia’s LFPAK56 package uses a copper clip which is soldered in a single operation to the surface of the die. This reduces spreading resistance and gives LFPAK56 superior electrical and thermal characteristics as well as increased reliability. The new PSMN0R9-30ULD and PSMN1R0-40ULD N-channel MOSFETs in the enhanced SOT1023A package feature a creepage distance of 1.5mm and a clearance distance of 1.55mm. The PSMN0R9-30ULD device is rated at 30 V, offering 0.87 mΩ and 300 A, the PSMN1R0-40ULD is rated at 40 V, with 1.1 mΩ and 280 A.


Comments Eric Su, International Product Marketing Manager: “UL2595 is an important US standard which could well be adopted by other international regulatory bodies. Also, equipment manufacturers prefer to design one global product that meets the toughest standard, rather than have multiple versions for different geographic locations. Therefore it is important that designers are aware that regular Power-SO8 devices will not pass UL2595, but that there is a compliant drop-in replacement available.”


The PSMN0R9-30ULD and PSMN0R9-40ULD MOSFETs are part of Nexperia’s NextPowerS3 family of devices that offer a combination of low RDS(on), high maximum current and strong safe operating area (SOA), perfect for battery-powered motor control applications.
