Here is an image showing the pin diagram of this transistor.The BD136-16 transistor can have a current gain of 100 to 250. The gain of the BD136 will be in the range from 40 to 250, for the BD136-10 it will be in the range from 63 to 160, for the BD136-6 it will be in the range from 40 to 100.The complementary NPN transistor to the BD136-16 is the BD135-16.The BCP51 (SOT-223), BCP51-16 (SOT-223), BCX51 (SOT-89) and BCX51-16 (SOT-89) is the SMD version of the BD136-16 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD136-16 with the 2SA1214, 2SB1142, 2SB1143, 2SB1165, 2SB1166, 2SB744, 2SB744A, 2SB986, BD132, BD136G, BD138, BD138-16, BD138G, BD140, BD140-16, BD140G, BD166, BD168, BD170, BD176, BD176-16, BD178, BD180, BD180G, BD188, BD190, BD227, BD229, BD231, BD234, BD234G, BD236, BD236G, BD238, BD238G, BD376, BD376-16, BD378, BD378-16, BD380, BD380-16, BD786, BD788, BD788G, BD790, KSB744, KSB744A, KSE171, KSE172, MJE171, MJE171G, MJE172, MJE172G, MJE235, MJE252, MJE711 or MJE712.
