Here is an image showing the pin diagram of this transistor.The BC850BW transistor can have a current gain of 200 to 450. The gain of the BC850AW will be in the range from 110 to 220, for the BC850CW it will be in the range from 420 to 800, for the BC850W it will be in the range from 110 to 800.The complementary PNP transistor to the BC850BW is the BC860BW.You can replace the BC850BW with the 2SC4116, BC817W, BC846BW, BC846W, BC847BW, BC847W or FJX945.
