This UPS1040e3 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,
JANTXV, and JANS are available by
adding MQ, MX, MV, or MSP prefixes
respectively to part numbers. For
example, designate MXUPS1040e3 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)
