Here is an image showing the pin diagram of this transistor.The BCW65B transistor can have a current gain of 160 to 400. The gain of the BCW65 will be in the range from 100 to 630, for the BCW65A it will be in the range from 100 to 250, for the BCW65C it will be in the range from 250 to 630.The complementary PNP transistor to the BCW65B is the BCW67B.You can replace the BCW65B with the BCW66, BCW66G or FMMT619.
