Power MOSFETs Can Beat The Heat

Introduced as the first thermally enhanced SC-70 power MOSFETS on the market, the latest LITTLE FOOT series provide a thermal resistance of 35ûC/W for single-channel devices and 80ûC/W for dual channel parts. This is cited as a 67% and 73% improvement, respectively, compared to similar devices in a larger TSSOP-8. The lower thermal resistance increases power dissipation to a maximum of 1W in the single-channel device. In addition, these MOSFETs also provide ESD protection up to 2 kV. Prices range from $0.35 to $0.39 each/100,000. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (610) 644-1300.
