The 2SC3708-S is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SC3708-S transistor can have a current gain of 140 to 280. The gain of the 2SC3708 will be in the range from 100 to 400, for the 2SC3708-R it will be in the range from 100 to 200, for the 2SC3708-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SC3708-S might only be marked "C3708-S".The complementary PNP transistor to the 2SC3708-S is the 2SA1450-S.The 2SC3438 (SOT-89) is the SMD version of the 2SC3708-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3708-S with the 2SC1509, 2SC2274K, 2SC2383, 2SC3228, 2SC3244, 2SC3332, 2SC3332-S, 2SC3939, 2SD1211, 2SD438, 2SD667, KSC1009C, KSC2383, KSP8099C, KTC1006 or KTC3228.
