Small package n-channel MOSFETs target automotive LEDs
The 60V SSM3K341R and the 100V SSM3K361R deliver low ON-resistance of 36mΩ and 65mΩ respectively and are qualified according to the AEC-Q101 standard. As a result, they are aimed at power management applications such as DC-DC converter or load switch applications which are of increasing importance for the ever developing 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. The SSM3K341R and SSM3K361R small-package MOSFETS address this demand with the typical RDS(ON) ratings of 36mΩ and 65mΩ at a VGS of 4.5V. In addition, both devices support a maximum channel temperature of 175°C for widespread use in a range of automotive applications.
Both new devices reduce heat dissipation resulting from turn-on losses by approximately 65% against Toshiba’s previous products. In addition, the MOSFETs are housed in compact SOT-23F flat lead type packages. These reduce PCB footprint by approximately 64% compared to a conventional SOT-89 package, while maintaining a maximum level of 2.4W power dissipation.
