Here is an image showing the pin diagram of this transistor.The 2SD1133-B transistor can have a current gain of 60 to 120. The gain of the 2SD1133 will be in the range from 60 to 320, for the 2SD1133-C it will be in the range from 100 to 200, for the 2SD1133-D it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD1133-B might only be marked "D1133-B".The complementary PNP transistor to the 2SD1133-B is the 2SB857-B.You can replace the 2SD1133-B with the 2N5293, 2N5294, 2N6290, 2N6290G, 2N6291, 2N6292, 2N6292G, 2N6293, 2N6473, 2N6487, 2N6487G, 2N6488, 2N6488G, 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2233, 2SC2334, 2SC3179, 2SC3851, 2SC3851A, 2SC4511, 2SC4512, 2SC789, 2SD1134, 2SD1134-B, 2SD1265, 2SD1265A, 2SD1267, 2SD1267A, 2SD1269, 2SD1269-R, 2SD1270, 2SD1270-R, 2SD1271, 2SD1271-R, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1356, 2SD1407, 2SD1407A, 2SD1408, 2SD1568, 2SD1588, 2SD2059, 2SD2060, 2SD362, 2SD389, 2SD389A, 2SD476, 2SD476-B, 2SD476A, 2SD476A-B, 2SD525, 2SD526, 2SD568, 2SD568-L, 2SD569, 2SD569-L, 2SD613, 2SD613-D, 2SD743, 2SD743-R, 2SD743A, 2SD743A-R, 2SD812, 2SD812-Q, 2SD823, 2SD857, 2SD857A, 2SD866, 2SD866-R, 2SD866A, 2SD866A-R, BD203, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD707, BD709, BD711, BD743A, BD743B, BD743C, BD797, BD799, BD801, BD807, BD809, BD907, BD909, BD911, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSD1408, KSD1588, KSD362, KSD526, KSD568, KSD568-O, KSD569, KSD569-O, KTC1003, KTD2059, KTD2060, NTE152 or NTE196.
