International Rectifier AUIRL7732S2/AUIRL7736M2 motor vehicle MOSFET

International Rectifier has introduced a motor vehicle DirectFET2 power MOSFET chipset optimised for DC-DC applications used in internal combustion engine cars, and hybrid and electric vehicles.

The 40 V logic level gate drive chipset comprises the AUIRL7732S2 MOSFET and AUIRL7736M2 MOSFET optimised to help minimise switching and conduction losses in DC-DC converters.

The devices may also be used in more generic heavy load applications such as inverter drives on pumps and fans and relay replacement in junction box applications.

The AUIRL7732S2 logic level MOSFET features low gate charge and a PCB footprint 38% smaller than an SO-8 package making it suitable for the control MOSFET position in a synchronous buck converter.

The AUIRL7736M2 MOSFET is applicable for the synchronous switch position and features low Rds(on) and PCB footprint the same size as a 5x6 PQFN or SO-8 package. The low inductance of the devices enables better switching performance at higher frequencies than traditional MOSFETs.
