KEY FEATURES
DESCRIPTION
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.
Very low thermal resistance package
RoHS Compliant with e3 suffix part
number
Guard-ring-die construction for transient
protection
Efficient heat path with Integral locking
bottom metal tab
Low forward voltage
Full metallic bottom eliminates flux
entrapment
Compatible with automatic insertion
Low profile-maximum height of 1mm
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
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)
