Here is an image showing the pin diagram of this transistor.The 2SA1283-C transistor can have a current gain of 55 to 110. The gain of the 2SA1283 will be in the range from 55 to 300, for the 2SA1283-D it will be in the range from 90 to 180, for the 2SA1283-E it will be in the range from 150 to 300.Sometimes the "2S" prefix is not marked on the package - the 2SA1283-C might only be marked "A1283-C".The complementary NPN transistor to the 2SA1283-C is the 2SC3243-C.The 2SA1364 (SOT-89), 2SA1364-C (SOT-89), BCP52 (SOT-223), BSR30 (SOT-89), FMMTA55 (SOT-23), KST55 (SOT-23) and MMBT4354 (SOT-23) is the SMD version of the 2SA1283-C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
