Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD138G is the BD137G.The BCP52 (SOT-223) is the SMD version of the BD138G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD138G with the BD138, BD140, BD140G, BD168, BD170, BD178, BD180, BD180G, BD190, BD229, BD231, BD236, BD236G, BD238, BD238G, BD378, BD380, BD788, BD788G, BD790, BD792, MJE235, MJE252, MJE254, MJE711 or MJE712.
