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”. The new products reduce heat dissipation resulting from turn-on loss by approximately 65% against Toshiba previous products[2]. 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.
