Two MOSFETs are compact for automotive use

The 60V SSM3K341R and the 100V SSM3K361R are qualified according to the AEC-Q101 standard. They are suitable for use in power management, including DC/DC converter or load switch applications for electronic systems in vehicles.

Increased industry demand for power-saving LEDs has seen growth in requirements for the n-channel MOSFETs that are used as switches for LED drivers. These small-package MOSFETS from Toshiba Electronics E, uropeaddress RDS(ON) ratings (at VGS 4.5V) of 36mΩ and 65mΩ respectively. Both devices support a maximum channel temperature of 175°C, for a range of automotive applications. 

The MOSFETs reduce heat dissipation resulting from turn-on losses by approximately 65% against the company’s previous products. They are housed in compact SOT-23F flat lead type packages to reduce PCB footprint by approximately 64% compared to a conventional SOT-89 package, while maintaining a maximum level of 2.4W power dissipation.
