Here is an image showing the pin diagram of this transistor.The 2SD2053-P transistor can have a current gain of 100 to 200. The gain of the 2SD2053 will be in the range from 60 to 200, for the 2SD2053-Q it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SD2053-P might only be marked "D2053-P".The complementary PNP transistor to the 2SD2053-P is the 2SB1362-P.You can replace the 2SD2053-P with the 2SC4278, 2SC4278-E, 2SD1717, 2SD1717-P, 2SD1718, 2SD1718-P, 2SD2052, 2SD2052-P, MJW3281A or MJW3281AG.
