As Mobile applications, such as Smart Phones, continue to go smaller, thinner and lighter, board sizes also have the same size limitations, resulting in extremely dense circuit designs. Therefore, downsizing all components are a must and thermal management has become an even more important factor in board designs. Also, despite the limited space, the power supply circuit has even more loads with constantly growing data-communications and High-end High-tech functions. To solve these issues, Panasonic is announcing a new CSP Diode series, with features such as Ultra-small packaging. (0.6mm x 0.3mm), Industry top-level Low Forward Voltage (15% reduction), and Industry top-level thermal performance (33% heat reduction) . This series has a line-up of 16 parts to fit all customer designs and requirements.
