About the Infineon Technologies SI44 Series

The Infineon Technologies SI44 Series series groups 7 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), drain to source voltage of 30 V and drive voltage (Max rds on, min rds on) of 4.5V, 10V. Variants differ by current - continuous drain (Id) @ 25°C, FET type and gate charge (Qg) (Max) @ vgs, so you can match the exact current - continuous drain (Id) @ 25°C your application requires using the selection guide below. The range mixes active and legacy part numbers, so you can source both current Infineon Technologies SI44 Series variants and discontinued ones from a single page.
