Here is an image showing the pin diagram of this transistor.The 2SC3787-S transistor can have a current gain of 140 to 280. The gain of the 2SC3787 will be in the range from 100 to 400, for the 2SC3787-R it will be in the range from 100 to 200, for the 2SC3787-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SC3787-S might only be marked "C3787-S".The complementary PNP transistor to the 2SC3787-S is the 2SA1477-S.You can replace the 2SC3787-S with the 2SC1565A, 2SC2690A, 2SC2911, 2SC2911-S, 2SC2912, 2SC2912-S, 2SC3116, 2SC3116-S, 2SC3117, 2SC3117-S, 2SC3601, 2SC3902, 2SC3902-S, 2SC3956, BD127, BD128, KSC2690A, MJE344, MJE344G or TTC004B.
