Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD948 is the BD947.The BDP948 (SOT-223) is the SMD version of the BD948 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD948 with the 2SA770, 2SA771, BD202, BD204, BD244, BD244A, BD244B, BD302, BD304, BD534, BD536, BD538, BD540A, BD540B, BD544A, BD544B, BD546A, BD546B, BD796, BD798, BD800, BD808, BD810, BD950, BD952, BDT82, BDT82F, BDT84, BDT84F, BDX78, D45H11, D45H11FP or D45H8.
