About the NXP Semiconductors BUJ1 Series

The NXP Semiconductors BUJ1 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 current - collector cutoff of 100µA, FET type of NPN and mounting of Through Hole. Variants differ by case, current - collector (Ic) and DC current gain (hFE) (Min) @ ic, vce, so you can match the exact case your application requires using the selection guide below. All listed NXP Semiconductors BUJ1 Series part numbers are active and orderable.
