UPS540e3
5 A Schottky Barrier Rectifier
DESCRIPTION
This UPS540e3 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.

Options for screening in accordance with
MIL-PRF-19500 for JAN, JANTX, and
JANTXV are available by adding MQ, MX,
or MV prefixes respectively to part
numbers. For example, designate
MXUPS540e3 for a JANTX (consult
factory for Tin-Lead plating).
Optional 100% avionics screening
available by adding MA prefix for 100%
temperature cycle, thermal impedance
and 24 hours HTRB (consult factory for
Tin-Lead plating)
