About the IXYS DSI45 Series

The IXYS DSI45 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-247-2, current - average rectified of 45A and mounting of Through Hole. Variants differ by current - reverse leakage @ vr and voltage - DC reverse (Vr), so you can match the exact current - reverse leakage @ vr your application requires using the selection guide below. All listed IXYS DSI45 Series part numbers are active and orderable.
