UMA5817, UMA5818, and UMA5819  
ULTRAMITE™ SURFACE MOUNT  
SCHOTTKY BARRIER RECTIFIERS  
S C O T T S D A L E D I V I S I O N  
DESCRIPTION  
APPEARANCE  
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.  
UltraMite™

Options for screening in accordance with MIL-PRF-  
19500/586 for JAN, JANTX, JANTXV, and JANS  
are available by adding MQ, MX, MV, or MSP  
prefixes respectively to part numbers. For  
example, designate a MXUMAJ5819 for a JANTX  
screen.
