Here is an image showing the pin diagram of this transistor.The 2SA1313-O transistor can have a current gain of 70 to 140. The gain of the 2SA1313 will be in the range from 70 to 240, for the 2SA1313-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1313-O might only be marked "A1313-O".The complementary NPN transistor to the 2SA1313-O is the 2SC3325-O.You can replace the 2SA1313-O with the 2SA1518, 2SA1519, 2SA1520, 2SA1521, FMMT551, FMMTA55, FMMTA56, KST55, KST56, MMBT4354 or MMBT4356.
