Here is an image showing the pin diagram of this transistor.The 2SD1032 transistor can have a current gain of 40 to 250. The gain of the 2SD1032-P will be in the range from 120 to 250, for the 2SD1032-Q it will be in the range from 70 to 150, for the 2SD1032-R it will be in the range from 40 to 90.Sometimes the "2S" prefix is not marked on the package - the 2SD1032 might only be marked "D1032".The complementary PNP transistor to the 2SD1032 is the 2SB812.You can replace the 2SD1032 with the 2SD1032A, 2SD858, BD245A, BD245B, BD245C, BD249A, BD249B, BD249C, BDV91, BDV93, BDV95 or TIP35CA.
