MOSFETs for Load Switches in LED Driver Applications
Toshiba Corporation's Storage and Electronic Devices Solutions Company today announced the launch of N-channel MOSFETs in small packages for load switches in LED driver applications, including automotive dashboard meters and headlights and LED TV backlights, that are claimed to be in the industry's leading-class for low on-resistance. Shipments of the new products start from today.
Along with the increased use of power saving LEDs, demand for N-channel MOSFETs, used as switches for LED drivers has also increased. To meet demand, Toshiba has added two small-package MOSFETS with the industry’s leading-class low on-resistance to its line-up, the 60V SSM3K341R and the 100V SSM3K361R.
Main specifications of the new devices include: SSM3K341R, VGSS ±20V, ID 6A, Rds(on) at VGS=4.5V of 36 milliOhms, and typical CISS of 550pF; SSM3K361R VGSS ±20V, ID 3.5A, Rds(on) at VGS=4.5V of 65 milliOhms, and typical CISS of 430pF.
The new products reduce heat dissipation resulting from turn-on loss by approximately 65% against Toshiba previous products. Also, the MOSFETs use an SOT-23F small-size flat lead type package, which maintains the same level of heat dissipation while reducing the footprint by approximately 64% compared to a conventional SOT-89 package. Both products are AEC-Q101 qualified for automotive applications.
