| UPS540E3 5 A Schottky Barrier Rectifier DESCRIPTION KEY FEATURES WWW .Microsemi .C OM 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(R) 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.

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) APPLICATIONS/BENEFITS Switching and Regulating Power Supplies.
