True chip-scale packaging is available from International
Rectifier. The IR140CPS surface-mount Schottky
rectifier has been designed for applications requiring low
forward drop and very small foot prints on PC boards.
Typical applications are in disk drives, switching power
supplies, converters, free-wheeling diodes, battery
charging, and reverse battery protection.
Small foot print, surface mountable
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
The Flipky
TM
package, is one-fifth the footprint of a
comparable SMA package and has a profile of less then
.8mm. Combined with the low thermal resistance of the
die level device, this makes the Flipky
TM
the best device
for application where printed circuit board space is at a
premium and in extremely thin application environments
such as battery packs, cell phones and PCMCIA cards.
