Small automotive power MOSFET package delivers reliability and efficiency

Nexperia has announced the availability of its automotive power MOSFETs in the new, LFPAK33, thermally-enhanced, loss-free package which has a footprint more than 80% smaller than industry standard devices. The devices also feature a significantly lower resistance responding to growing industry pressure to reduce the size of modules in the car while continuing to improve energy efficiency and reliability. The MOSFETs enable the power infrastructure that allows next-generation automotive subsystems such as radar and ADAS technology to operate reliably and efficiently.   The package uses a copper clip design to reduce the package resistance and inductance which in turn reduces the RDS(on) and losses of the MOSFET. The resulting package has an ultra-compact footprint of 10.9mm2, and because no wires or glue is used internally, operating temperatures of up to 175oC Tj max are possible. Devices can handle up to 70A, and the extensive product portfolio includes devices that range between 30V – 100V and an RDS(on) as low as 6.3mOhm.   “As more subsystems are crammed into cars the need for rugged, compact power systems is becoming ever greater,” said Richard Ogden, international product marketing engineer at Nexperia. “This extension of our LFPAK portfolio provides designers with more product choices than anywhere else on the market today.”   Target applications include connected auto modules, next generation engine management systems; chassis and safety technology; LED lighting; relay replacement; C2X, radar, infotainment and navigation systems; and ADAS.
