NXP Semiconductors N.V. has unleashed 54 automotive-qualified MOSFETs in an LFPAK56 package that claim to offer excellent performance and reliability. The devices also promise more than 55 per cent PCB space compared to DPAK. The LFPAK56 MOSFETs target automotive applications, particularly in the areas of powertrain, body and security, and chassis and safety, added NXP.

The power MOSFETs are available at voltage grades of 30V, 40V, 60V, 80V and 100V, with excellent RDS(on) performance and current handling, indicated the company.

The BUK9Y3R0-40E features a low RDS(on) of only 3mΩ at 40V, and the ability to handle currents as high as 100A. The product is geared for motor drive applications such as those found in seat control, window lifters, windscreen wipers and other body control applications as well as pumps and fans.

The BUK9Y59-60E has an RDS(on) of 59mΩ at 60V and is aimed at engine management systems such as petrol direct injection and diesel direct injection, which typically require multiple parts per system, due to its small size as well as its excellent ruggedness capability.

The BUK9Y38-100E touts an RDS(on) of 38mΩ at 100V and is engineered for automotive LED applications due to its ultra-low package inductance and small footprint.

Whereas QFN micro-leads are fully encapsulated, restricting movement that can cause cracks and contamination, the LFPAK gull-wing leads allow for thermal expansion and mechanical strain due to PCB bending and flexing. The integrated copper clip also claims to provide low electrical resistance, low thermal resistance, low inductance and high reliability. As with other NXP Trench 6 automotive MOSFETs, the LFPAK56 MOSFETs are fully AEC-Q101 qualified, and have successfully completed extended lifetime testing at 175ºC for more than 1,600 hours and offer extremely low PPM levels.
