Industry's smallest 1 A, 40 V Schottky diode
24 September 2003
Power Electronics / Power Management
International Rectifier has introduced what it claims is the smallest Schottky diode in the industry. The IR140CSP FlipKY device uses standard ball-grid array (BGA) technology, and occupies a total area of 2,25 mm2 - or 86% smaller than standard SMA package, and as much as 32% smaller than similar lead-less devices. The diode is a 1 A, 40 V Schottky in a four-ball, 1,5 x 1,5 mm outline with a profile of less than 0,8 mm. FlipKY eliminates the lead frame and epoxy traditionally used in other devices, and targets applications in handheld, portable equipment. Since the IR140CSP is small, it allows strategic placement, much reducing stray inductance and increasing overall circuit efficiency. The FlipKY device is lead-less, and minimises lead inductance compared to lead frame and axial packages.
