AVX introduces leadless Schottky diodes for SMPS applications

AVX has introduced a new series of Schottky-barrier rectifier diodes uniquely packaged as leadless chips. Eliminating the standard lead-frame wire bond provides the chip with top-bottom symmetry, which enables better heat transfer, better current handling capability than SOD devices, and fewer mounting problems. Available in several case sizes and a range of current values spanning 0.1 to 8 A, the new leadless chip form Schottky rectifier diodes are well suited for applications including switch-mode power supplies, high-frequency rectification, portable battery-powered devices, and reverse-bias protection. AVX's low-loss, high-efficiency Schottky rectifier diodes are lead-free, halogen-free, and RoHS-compliant. Housed in cases composed of FRP substrates with epoxy underfill—a UL 94V-0 class package material—the diodes are available in 0603, 0805, 1206, 2010, 2114, and 3220 case sizes and in both standard and thin thicknesses. Mechanically robust, the new Schottky diodes are also available in a range of voltages, spanning 20 to 200 V, and in both standard and low V_f. The diodes' terminations are 100% tin-plated and are solderable per MIL-STD-750, method 2026. The 2114 case size Schottky rectifier diodes are packaged on 13" reels in quantities of 5000, the 3220 case size diodes are packaged on 13" reels in quantities of 3000, and all other case sizes are packaged on 7" reel in quantities of 3000.
