Here is an image showing the pin diagram of this transistor.The 2SA1620 transistor can have a current gain of 70 to 240. The gain of the 2SA1620-O will be in the range from 70 to 140, for the 2SA1620-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1620 might only be marked "A1620".The complementary NPN transistor to the 2SA1620 is the 2SC4209.You can replace the 2SA1620 with the 2N5401S, FMMT555, FMMTA56, KST5401, KST56, MMBT4356, MMBT5401 or PMBT5401.
