UPS340e3
3 A LOW Vf Schottky Barrier Rectifier
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.

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 MXUPS340e3 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)
