AVX intros unique lead-less schottky rectifier diodes for switching power supply apps

USA: AVX Corp. has introduced a new series of Schottky barrier rectifier diodes uniquely packaged as lead-less 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 0.1A to 8A, the new lead-less chip form Schottky rectifier diodes are ideal for applications including switch mode power supplies, high frequency rectification, portable battery powered devices, and reverse bias protection.

“A complement to the recent extension of AVX’s inductor lines, the new Schottky barrier rectifier diodes allow us to provide solutions for all of the major passives needs of switching power supply designers,” said Mike Muir, North American product manger for circuit protection products at AVX.

AVX’s low power 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 cases sizes and in both standard and thin thicknesses.
Mechanically robust, the new Schottky diodes are also available in a range of voltages, spanning 20V to 200V, and in both standard and low Vf. 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.
