DESCRIPTION
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
