About the Vishay Vishay SI44 Series series
The Vishay Vishay SI44 Series series groups 32 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 8-SOIC (0.154\", 3.90mm Width), FET feature of - and mounting type of Surface Mount. Variants differ by current - continuous drain (Id) @ 25°C, drain to source voltage and drive voltage (Max rds on, min rds on), so you can match the exact current - continuous drain (Id) @ 25°C your application requires using the selection guide below. All listed Vishay SI44 Series part numbers are active and orderable.
