UPS340E3/TR13

UPS340e3 3 A LOW Vf Schottky Barrier Rectifier KEY FEATURES DESCRIPTION This UPS340e3 in the Powermite3 package is a high efficiency Schottky rectifier that is also RoHS compliant offering high current/power capabilities previously found only in much larger packages. They are ideal for SMD applications that operate at high frequencies. In addition to its size advantages, the Powermite3® package includes a full metallic bottom that eliminates the possibility of solder flux entrapment during assembly and a unique locking tab act as an efficient heat path to the heat-sink mounting. Its innovative design makes this device ideal for use with automatic insertion equipment. ƒ Very low thermal resistance package ƒ RoHS Compliant with e3 suffix part number ƒ Guard-ring-die construction for transient protection ƒ Efficient heat path with Integral locking bottom metal tab ƒ Low forward voltage ƒ Full metallic bottom eliminates flux entrapment ƒ Compatible with automatic insertion ƒ Low profile-maximum height of 1mm IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com WWW .
