Automotive N-/P-Channel SSMx MOSFETs Toshiba Automotive N- and P-Channel SSMx MOSFETs are available in multiple package styles to cover various automotive applications in 12V to 48V battery systems. The AEC-qualified SSMx MOSFETS benefit from Toshiba's state-of-the-art wafer processes that suppress switching noise. The wafer processes and low resistance allow these MOSFETs to achieve a leading level of low on-resistance. The low resistance contributes to reduced energy loss and miniaturization of applications.
