MOSFET Solutions for 48 V Automotive Systems

onsemi's automotive MOSFETs are available in a range of package options, including TO-leadless and DPAK. The devices offer compact and efficient solutions with high power density and a reduction in conduction losses.

80 V Automotive MOSFETs:
onsemi's family of 80 V automotive-qualified MOSFETs provide high power density and robustness, addressing the size and efficiency needs of 48 V systems. Advanced silicon and packaging technology are combined to provide the extremely low R_DS(ON), improved figure of merit (FOM), and lower power dissipation to address evolving efficiency standards. onsemi's PowerTrench® MOSFETs with shielded-gate technology have resulted in very low switching losses without requiring external snubbers.

100 V Automotive MOSFETs:
onsemi's family of 100 V power MOSFETs are available in a 5 mm x 6 mm SO-8FL package designed for compact and efficient designs with high thermal performance.  The devices offer best-in-class FOM, which enables high efficiency and low power dissipation.

PowerTrench® MOSFETs in TO-Leadless Packaging:
TO-LL technology offers an extremely low device resistance, footprint, and enables exceptional EMI behavior.  This technology is now offered in a range of voltage options specifically designed and qualified for automotive applications.

The combination of onsemi's latest PowerTrench shielded gate trench technology along with the TO-LL package gives onsemi's leadless MOSFET products low R_DS(ON). In addition, superior silicon technology and package design results in excellent switching and EMI performance. Compared to other discrete packages, the number of parallel MOSFETs needed in high-current applications can be significantly reduced, if not eliminated, leading to overall lower system costs.
