3 A LOW Vf Schottky Barrier Rectifier

DESCRIPTION

package, these high efficiency ultrafast

rectifiers offer the power handing

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,

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.
