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.
