Description

The UMA5817 thru UMA5819 UltraMite™ series offers small efficient surface mount packaging with the same electrical features as the popular 1N5817, 1N5818, and 1N5819 Schottky rectifiers. It provides the same size footprint as other small surface mount DO-214AC or BA package options except with a much lower profile height. Its configuration in a "2010 MELF" style robust package design prevents lead damage to terminals and also minimizes parasitics by eliminating internal wire bonds and providing very short internal conduction paths.
