About the KYOCERA AVX UCQS Series

The KYOCERA AVX UCQS Series series groups 2 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. Every variant in the range shares a common case of TO-263-3, D²Pak (2 Leads + Tab), TO-263AB, diode type of Schottky and mounting of Surface Mount. Variants differ by current - reverse leakage @ vr and voltage - forward (Vf) (Max) @ if, so you can match the exact current - reverse leakage @ vr your application requires using the selection guide below. All listed KYOCERA AVX UCQS Series part numbers are active and orderable.
