Here is an image showing the pin diagram of this transistor.The 2SB1417A transistor can have a current gain of 70 to 250. The gain of the 2SB1417A-P will be in the range from 120 to 250, for the 2SB1417A-Q it will be in the range from 70 to 150.Sometimes the "2S" prefix is not marked on the package - the 2SB1417A might only be marked "B1417A".The complementary NPN transistor to the 2SB1417A is the 2SD2137A.The BDP952 (SOT-223) is the SMD version of the 2SB1417A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
