Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD940 is the BD939.The BDP954 (SOT-223) and BDP956 (SOT-223) is the SMD version of the BD940 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD940 with the BD242C, BD244C, BD540C, BD802, BD940F, BD942, BD942F, BD954, BD956, BDT86, BDT86F, BDT88, BDT88F, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
