FCSP240LTR Vishay High Power Products FlipKY Chip Scale Package Schottky Barrier Rectifier FEATURES Ultra low V per footprint area F Low leakage RoHS Low thermal resistance COMPLIANT One-fifth footprint of SMA Super low profile (0.6 mm) Available tested on tape and reel APPLICATIONS Reverse polarity protection FlipKY Current steering Freewheeling Flyback Oring DESCRIPTION Vishay s FlipKY product family utilizes wafer level chip scale packaging to deliver Schottky diodes with the lowest V to PCB footprint area in industry. The four F PRODUCT SUMMARY bump 1.5 x 1.5 mm devices can deliver up to 1.5 A and 2 occupy only 2.3 mm of board space. The anode and I 1.5 A F(AV) cathode connections are made through solder bump pads on V 40 V R 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.
