Here is an image showing the pin diagram of this transistor.The 2SC3780-F transistor can have a current gain of 160 to 320. The gain of the 2SC3780 will be in the range from 40 to 320, for the 2SC3780-C it will be in the range from 40 to 80, for the 2SC3780-D it will be in the range from 60 to 120, for the 2SC3780-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC3780-F might only be marked "C3780-F".The complementary PNP transistor to the 2SC3780-F is the 2SA1474-F.You can replace the 2SC3780-F with the 2SC1826, 2SC1985, 2SC1986, 2SC2075, 2SC2275, 2SC2275-P, 2SC2528, 2SC3179, 2SC3851, 2SC3851A, 2SC4007, 2SC4007-F, 2SC4008, 2SC4008-F, 2SC4550, 2SC4551, 2SC4552, 2SD1134, 2SD1134-D, 2SD1266, 2SD1266-O, 2SD1266A, 2SD1266A-O, 2SD1274, 2SD1274A, 2SD1274B, 2SD1562, 2SD1562-F, 2SD1761, 2SD1761-F, 2SD1763, 2SD1763-F, 2SD2012, 2SD2061, 2SD2394, 2SD2394-F, 2SD313, 2SD313F, 2SD613, 2SD613-F, 2SD823, BD203, BD239A, BD239B, BD239C, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD539D, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD949, BD951, BD953, BD955, BDT29A, BDT29B, BDT29C, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDX77, D44H11, D44H11FP, D44H8, KSD2012, KSD2012-G, MJE15028, MJE15028G, TIP41D or TIP42D.
