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