Here is an image showing the pin diagram of this transistor.The 2SD325-C transistor can have a current gain of 40 to 80. The gain of the 2SD325 will be in the range from 40 to 320, for the 2SD325-D it will be in the range from 60 to 120, for the 2SD325-E it will be in the range from 100 to 200, for the 2SD325-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD325-C might only be marked "D325-C".The complementary PNP transistor to the 2SD325-C is the 2SB511-C.You can replace the 2SD325-C with the 2N5293, 2N5294, 2N5295, 2N5296, 2N5297, 2N5298, 2N5490, 2N5492, 2N5494, 2N5496, 2N6098, 2N6099, 2N6121, 2N6122, 2N6129, 2N6130, 2N6290, 2N6290G, 2N6291, 2N6292, 2N6292G, 2N6293, 2N6486, 2N6486G, 2N6487, 2N6487G, 2SC1061, 2SC1418, 2SC1419, 2SC1826, 2SC1985, 2SC2233, 2SC3179, 2SC3851, 2SC789, 2SC789-R, 2SC790, 2SC790-R, 2SD1265, 2SD1267, 2SD1267-R, 2SD1568, 2SD1568-M, 2SD1588, 2SD1588-M, 2SD234, 2SD234R, 2SD235, 2SD235-R, 2SD288, 2SD288-R, 2SD313, 2SD313C, 2SD330, 2SD330C, 2SD362, 2SD362-R, 2SD389, 2SD568, 2SD568-M, 2SD856, 2SD856-R, 2SD857, 2SD857-R, BD201, BD203, BD239, BD239A, BD241, BD241A, BD243, BD243A, BD301, BD303, BD533, BD533K, BD535, BD535K, BD539, BD539A, BD705, BD707, BD735, BD737, BD743, BD743A, BD795, BD797, BD807, BD905, BD907, BD933, BD933F, BD935, BD935F, BD949, BDT81, BDT81F, BDT91, BDT91F, KSD1588, KSD1588-R, KSD288, KSD288-R, KSD362, KSD362-R, KSD568, KSD568-R, KTC1003, MJE2801T, MJE3055T, MJE3055TG or NTE196.
