Here is an image showing the pin diagram of this transistor.The BCW65A transistor can have a current gain of 100 to 250. The gain of the BCW65 will be in the range from 100 to 630, for the BCW65B it will be in the range from 160 to 400, for the BCW65C it will be in the range from 250 to 630.The complementary PNP transistor to the BCW65A is the BCW67A.You can replace the BCW65A with the BCW66, BCW66F, FMMT491, FMMT491Q, FMMT619 or MMBT2222A.
