The UPS5817e3 and UPS5819e3 offer a small and powerful surface mount package that is RoHS compliant for a 1 Amp rated Schottky. These ratings are found only in much larger packages. They are ideal for surface mount applications that operate at high frequencies with their "hot carrier" features that provide extremely fast switching. The very low thermal resistance of the patented Powermite 1TM package design with a full metallic bottom and unique locking tab act as an efficient heat path to a heat sink mounting permitting cooler operating junction temperatures for minimal reverse leakage currents and lower power loss. It is also ideal for automatic insertion equipment.
