International Rectifier has introduced four Schottky diodes that are smaller and more efficient than typical industry-standard Schottky devices. Offered in chip-scale packages (CSP), these 0.5A and 1.0A devices are siuted for handheld and portable equipment. The 30-volt IR0530CSP and 40-volt IR05H40CSP are 0.5A devices housed in a three-bump, CSP that occupies 1.1mm2 of board space with a profile of less than 0.6mm. The 30-volt IR130CSP and 40-volt IR1H40CSP are 1A BGA devices, occupying 2.3mm2 of board space. These new devices are available as lead-free and tape and reel versions.
