Here is an image showing the pin diagram of this transistor.The 2SD1380-Q transistor can have a current gain of 120 to 270. The gain of the 2SD1380 will be in the range from 82 to 390, for the 2SD1380-P it will be in the range from 82 to 180, for the 2SD1380-R it will be in the range from 180 to 390.Sometimes the "2S" prefix is not marked on the package - the 2SD1380-Q might only be marked "D1380-Q".The complementary PNP transistor to the 2SD1380-Q is the 2SB1009-Q.You can replace the 2SD1380-Q with the 2SC1162, 2SD1348, 2SD1682, 2SD1683, 2SD1722, 2SD1723, 2SD794, 2SD794A, BD131, BD187, BD189, BD233, BD233G, BD235, BD235G, BD375, BD377, BDX35, BDX36, KSD794, KSD794A, MJE222, MJE225, MJE521 or MJE521G.
