| UPS840E3 POWERMITE 3TM SURFACE MOUNT 8 AMP 40 V SCHOTTKY RECTIFIER SCOTTSDALE DIVISION DESCRIPTION The UPS840E3 offers a small and powerful surface mount package that is RoHS compliant for a 40 Volt 8 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 3TM 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.
