Here is an image showing the pin diagram of this transistor.The 2SD325-F transistor can have a current gain of 160 to 320. The gain of the 2SD325 will be in the range from 40 to 320, for the 2SD325-C it will be in the range from 40 to 80, 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.Sometimes the "2S" prefix is not marked on the package - the 2SD325-F might only be marked "D325-F".The complementary PNP transistor to the 2SD325-F is the 2SB511-F.You can replace the 2SD325-F with the 2SC1061, 2SC1061-D, 2SC1418, 2SC1418-D, 2SC1419, 2SC1419-D, 2SC1826, 2SC1985, 2SC3179, 2SC3851, 2SC4550, 2SC4551, 2SC4552, 2SD1133, 2SD1133-D, 2SD1134, 2SD1134-D, 2SD1266, 2SD1266-O, 2SD1761, 2SD1761-F, 2SD1762, 2SD1762F, 2SD2012, 2SD2061, 2SD2061F, 2SD2394, 2SD2394-F, 2SD2395, 2SD2395-F, 2SD313, 2SD313F, 2SD330, 2SD330F, 2SD612K, 2SD612K-F, 2SD795, 2SD795-P, BD201, BD203, BD239, BD239A, BD241, BD241A, BD243, BD243A, BD301, BD303, BD533, BD535, BD539, BD539A, BD543, BD543A, BD545, BD545A, BD735, BD737, BD795, BD797, BD807, BD947, BD949, BDT81, BDT81F, D44H8, KSD2012 or KSD2012-G.
