Here is an image showing the pin diagram of this transistor.The BC850W transistor can have a current gain of 110 to 800. The gain of the BC850AW will be in the range from 110 to 220, for the BC850BW it will be in the range from 200 to 450, for the BC850CW it will be in the range from 420 to 800.The complementary PNP transistor to the BC850W is the BC860W.You can replace the BC850W with the BC846W or BC847W.
