Here is an image showing the pin diagram of this transistor.The BC857BW transistor can have a current gain of 200 to 450. The gain of the BC857AW will be in the range from 110 to 220, for the BC857CW it will be in the range from 420 to 800, for the BC857W it will be in the range from 110 to 800.The complementary NPN transistor to the BC857BW is the BC847BW.You can replace the BC857BW with the BC807W, BC856BW, BC856W, BC860BW, BC860W or FJX733.
