POWERMITE 1™ SURFACE MOUNT

1 AMP 20 and 40 V SCHOTTKY RECTIFIERS

WWW.Microsemi .COM SCOTTSDALE DIVISION UPS5817e3 and UPS5819e3 UPS5817e3 & UPS5819e3 DESCRIPTION APPEARANCE 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 frequencie s 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. DO-216 Powermite 1™ IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS

  • Low profile DO-216 package (<1.1 mm)
  • RoHS compliant with e3 suffix part number
  • Small footprint area of 8.45 mm 2
  • 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
  • High current capability with low forward voltage
  • Guard-ring-die construction for transient protection
  • Silicon Schottky (hot carrier) rectifier for minimal t rr and minimal reverse recovery voltage
