MOSFETs boast leading on-resistance for load switching
Two compact, N-channel MOSFETs for load switching in automotive applications have been announced by Toshiba. The 60V SSM3K341R and the 100V SSM3K361R are qualified to AEC-Q101 standard. They are suitable for power management, including DC/DC converter or load switch applications which are increasingly used in 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. Toshiba’s SSM3K341R and SSM3K361R small-package MOSFETS address this demand class-leading typical RDS(ON) ratings (at VGS of 4.5V) of 36 and 65mOhm respectively. Both devices support a maximum channel temperature of 175 degree C, which enables wide spread use in a range of automotive applications.
Both MOSFETs reduce heat dissipation resulting from turn-on losses by approximately 65 per cent against the company’s previous products. The compact SOT-23F flat lead type packages reduce PCB footprint by approximately 64 per cent compared to a conventional SOT-89 package, says the company, while maintaining a maximum level of 2.4W power dissipation.
