UPS540 W ATE R TOW N DIVISI ON SCHOTTKY BARRIER RECTIFIER 0.5 AMP, 40 VOLT KEY FEATURES DESCRIPTION W W W . Microsemi . COM In Microsemi’s new Powermite SMT Package, these high efficiency Schottky rectifiers offer power handling 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, Powermite package features include a full metallic bottom that eliminates the possibility of solder flux entrapment during assembly, and a unique locking tab acts as an integral heat sink. Its innovative design makes this device ideal for use with automatic insertion equipment. !" Low Profile – Maximum height of 1.1 mm !" Footprint Area of 10 mm !" Low VF Provides Higher Efficiency !"
