Here is an image showing the pin diagram of this transistor.The BDP952 (SOT-223) and BDP954 (SOT-223) is the SMD version of the MJE172G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MJE172G with the BD180, BD180G, BD790, BD792, KSE172, MJE172, MJE252 or MJE254.
