Compact ON-resistance N-channel MOSFETs for automotive

Toshiba has developed a series of new high-efficiency N-channel MOSFETs for automotive applications that are based on the company’s advanced U-MOSVIII-H process technology. The XPN3R804NC and XPN7R104NC both have 40V voltage ratings, while the XPN6R706NC and XPN12006NC support 60V operation.

They all exhibit extremely low ON-resistance values, reaching down to 3.8mΩ (for the XPN3R804NC at 10V), plus minimal leakage current.

These MOSFETs are housed in surface-mount TSON Advance (WF) packages which ensure that board utilisation is kept to a minimum. They have a 3.3x3.6mm (typical) footprint and can replace devices with a size of 5x6mm. Through inclusion of wettable flank terminals, board mounting procedures and automated optical inspection (AOI) activities are also aided.

Fully AEC-Q101-compliant, these MOSFET devices are intended for deployment within automotive environments. Thanks to their inherent compactness, they can contribute significantly to a shrinkage in the size of vehicles’ electronic control units (ECUs). Other potential application scenarios where they may be utilised include switching regulators, DC-DC converters and motor drivers.
