About the Sanken 2SK2 Series

The Sanken 2SK2 Series series groups 3 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-220-3 Full Pack, drive voltage (Max rds on, min rds on) of 10V and FET feature of -. Variants differ by current - continuous drain (Id) @ 25°C, drain to source voltage and input capacitance (Ciss) (Max) @ vds, so you can match the exact current - continuous drain (Id) @ 25°C your application requires using the selection guide below. All listed Sanken 2SK2 Series part numbers are active and orderable.
