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.
KEY FEATURES
◾ 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
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)
