Here is an image showing the pin diagram of this transistor.The BC858W transistor can have a current gain of 110 to 800. The gain of the BC858AW will be in the range from 110 to 220, for the BC858BW it will be in the range from 200 to 450, for the BC858CW it will be in the range from 420 to 800.The complementary NPN transistor to the BC858W is the BC848W.You can replace the BC858W with the BC857W, BC859W or BC860W.
