Toshiba Introduces New, Compact N-Channel Power MOSFETs for Load Switching in Industrial, Automotive and Lighting Applications

October 17, 2017

60V SSM3K341R and the 100V SSM3K361R

IRVINE, Calif., – Toshiba America Electronic Components, Inc. (TAEC)* today announced the expansion of its lineup of automotive N-channel power MOSFETs with the addition of the 60V SSM3K341R and the 100V SSM3K361R. Housed in small SOT-23F packages, the new MOSFETs feature industry-leading1 low on-resistance and are suited to load switching in LED driver applications, including automotive dashboard meters and headlights and LED TV backlights. 

Increasing demand for power-saving LEDs has led to the growing use of N-channel MOSFETs as switches for LED drivers. Toshiba’s SSM3K341R and SSM3K361R address this demand with the industry’s best typical RDS(ON) ratings (@VGS=4.5V) of 36mΩ and 65mΩ, respectively. Additionally, both devices support a maximum channel temperature of 175°C, which enables them to be used in a wide range of industrial and automotive applications.

The SSM3K341R and SSM3K361R reduce heat dissipation resulting from turn-on loss by approximately 65 percent when compared to previous products2. The small package size of the new MOSFETs maintains the same level of heat dissipation while reducing the overall footprint by approximately 64 percent when compared to a conventional SOT-89 package. Both products are AEC-Q101 qualified for automotive applications.

Toshiba has also introduced four new MOSFETs with even smaller package sizes. The SSM6K341NU and SSM6K361NU utilize the SOT-1220 package; while the SSM3K341TU and SSM3K361TU are housed in UFM (2.0×2.1mm) packages. These MOSFETs feature the same low on-resistance as the SSM3K341R and SSM3K361R, while reducing the package mounting area by 43 percent and 40 percent, respectively.
