DESCRIPTION
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 1™ 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.

FEATURES
• Low profile DO-216 package (<1.1 mm)
• RoHS compliant with e3 suffix part number
• Small footprint area of 8.45 mm2
• Plastic package has Underwriters Laboratory
   Flammability classification 94V-0
• Unique locking tab on bottom acts as integral efficient
   heat path to heat sink (mounting substrate)
• Metal to silicon rectifier, majority carrier conduction

APPLICATIONS / BENEFITS
• High current capability with low forward voltage
• Guard-ring-die construction for transient protection
• Silicon Schottky (hot carrier) rectifier for minimal trr
   and minimal reverse recovery voltage
• Elimination of reverse-recovery oscillations to
   reduce need for EMI filtering
• For use in high-frequency switching power supplies,
   inverters, free wheeling, charge pump circuits and
   polarity protection applications
• Lower forward power loss and high efficiency
• Low inductive parasitics (<2nH) for minimal Ldi/dt
   effects
• Robust package configuration for pick-and-place
   handling
• Full-metallic bottom eliminates flux entrapment
• Small foot print with 0.100 x 0.160 inches (see
   mounting pad details on last page)
