Here is an image showing the pin diagram of this transistor.The BC297-6 transistor can have a current gain of 75 to 150. The gain of the BC297 will be in the range from 75 to 260, for the BC297-7 it will be in the range from 125 to 260.The complementary NPN transistor to the BC297-6 is the BC377-6.The 2SA1313 (SOT-23), 2SA1313-O (SOT-23), 2SA1518 (SOT-23), 2SA1519 (SOT-23), 2SA1520 (SOT-23) and 2SA1521 (SOT-23) is the SMD version of the BC297-6 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
