Here is an image showing the pin diagram of this transistor.The 2SD330 transistor can have a current gain of 40 to 320. The gain of the 2SD330C will be in the range from 40 to 80, for the 2SD330D it will be in the range from 60 to 120, for the 2SD330E it will be in the range from 100 to 200, for the 2SD330F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD330 might only be marked "D330".The complementary PNP transistor to the 2SD330 is the 2SB514.You can replace the 2SD330 with the 2SC1061, 2SC1418, 2SC1419, 2SC1826, 2SC1985, 2SC1986, 2SC2075, 2SC3179, 2SC3851, 2SC3851A, 2SD1274, 2SD1274A, 2SD1274B, 2SD313, 2SD613, 2SD823, BD203, BD239A, BD239B, BD239C, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD797, BD799, BD801, BD807, BD809, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F or BDX77.
