DESCRIPTION

Vishay's FlipKY® product family utilizes wafer level
chip scale packaging to deliver Schottky diodes with the

to PCB footprint area in industry. The four

F

1.5 A

40 V

lowest V
bump 1.5 x 1.5 mm devices can deliver up to 1.5 A and
occupy only 2.3 mm2 of board space. The anode and
cathode connections are made through solder bump pads on
one side of the silicon enabling designers to strategically
place the diodes on the PCB. This design not only minimizes
board space but also reduces thermal resistance and
inductance, which can improve overall circuit efficiency.

Typical applications include hand-held, portable equipment
such as cell phones, MP3 players, bluetooth, GPS, PDAs,
and portable hard disk drives where space savings and
performance are crucial.
