Here is an image showing the pin diagram of this transistor.The 2SA1283-E transistor can have a current gain of 150 to 300. The gain of the 2SA1283 will be in the range from 55 to 300, for the 2SA1283-C it will be in the range from 55 to 110, for the 2SA1283-D it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA1283-E might only be marked "A1283-E".The complementary NPN transistor to the 2SA1283-E is the 2SC3243-E.The 2SA1364 (SOT-89), 2SA1364-E (SOT-89), BSP31 (SOT-223), BSR31 (SOT-89), DXT2907A (SOT-89), DZT2907A (SOT-223), FJX2907A (SOT-323), FMMT2907A (SOT-23), FMMT2907AR (SOT-23), FMMTA55 (SOT-23), KN2907AS (SOT-23), KST2907A (SOT-23), KST55 (SOT-23), KTN2907AS (SOT-23), KTN2907AU (SOT-323), MMBT2907A (SOT-23), MMBT4354 (SOT-23), MMBT4355 (SOT-23), MMBTA55 (SOT-23), MMST2907A (SOT-323), PMBT2907A (SOT-23), PMST2907A (SOT-23), PZT2907A (SOT-223), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the 2SA1283-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1283-E with the 2SB1116A, 2SB647 or KSB1116A.
