DESCRIPTION
Vishay’s FlipKY
®
product family utilizes wafer level
chip scale packaging to deliver Schottky diodes with the
lowest V
F
to PCB footprint area in industry. The four
bump 1.5 mm x 1.5 mm devices can deliver up to 1.5 A and
occupy only 2.3 mm
2
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.
