Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the D45C10 is the D44C10.The BDP952 (SOT-223) is the SMD version of the D45C10 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the D45C10 with the 2N6041, 2N6041G, 2N6042, 2N6042G, 2N6126, 2N6134, 2N6475, 2N6476, 2N6491, 2N6491G, 2N6668, 2N6668G, 2SA1010, 2SA1010K, 2SA1010L, 2SA1010M, 2SA1077, 2SA1293, 2SA1293-O, 2SA1293-Y, 2SA1308, 2SA1308-O, 2SA1308-Y, 2SA1329, 2SA1329-O, 2SA1329-Y, 2SA1388, 2SA1388-O, 2SA1388-Y, 2SA1452, 2SA1452-O, 2SA1452-Y, 2SA1452A, 2SA1452A-O, 2SA1452A-Y, 2SA1488A, 2SA1634, 2SA1634-D, 2SA1634-E, 2SA1634-F, 2SA1635, 2SA1635-D, 2SA1635-E, 2SA1635-F, 2SA1725, 2SA1725-O, 2SA1725-P, 2SA1725-Y, 2SA1726, 2SA1726-O, 2SA1726-P, 2SA1726-Y, 2SA769, 2SA771, 2SB1016, 2SB1016-O, 2SB1016-R, 2SB1016-Y, 2SB1016A, 2SB1016A-O, 2SB1016A-Y, 2SB1017, 2SB1017-O, 2SB1017-R, 2SB1017-Y, 2SB1018, 2SB1018-O, 2SB1018-Y, 2SB1018A, 2SB1018A-O, 2SB1018A-Y, 2SB1020, 2SB1020A, 2SB1024, 2SB1090, 2SB1090-K, 2SB1090-L, 2SB1090-M, 2SB1227, 2SB1228, 2SB1251, 2SB1251-P, 2SB1251-Q, 2SB1252, 2SB1252-P, 2SB1252-Q, 2SB1367, 2SB1367-O, 2SB1367-R, 2SB1367-Y, 2SB1368, 2SB1368-O, 2SB1368-R, 2SB1368-Y, 2SB1481, 2SB1626, 2SB1626-O, 2SB1626-P, 2SB1626-Y, 2SB595, 2SB595-O, 2SB595-R, 2SB595-Y, 2SB596, 2SB596-O, 2SB596-R, 2SB596-Y, 2SB601, 2SB601-K, 2SB601-L, 2SB601-M, 2SB633, 2SB633-C, 2SB633-D, 2SB633-E, 2SB633-F, 2SB673, 2SB674, 2SB703, 2SB703-Q, 2SB703-R, 2SB703-S, 2SB703A, 2SB703A-Q, 2SB703A-R, 2SB703A-S, 2SB708, 2SB708-O, 2SB708-R, 2SB708-Y, 2SB747, 2SB747-P, 2SB747-Q, 2SB747-R, 2SB751A, 2SB751A-P, 2SB751A-Q, 2SB751A-R, 2SB762A, 2SB762A-P, 2SB762A-Q, 2SB762A-R, 2SB870, 2SB870-P, 2SB870-Q, 2SB870-R, 2SB885, 2SB886, 2SB942A, 2SB942A-P, 2SB942A-Q, 2SB942A-R, 2SB944, 2SB944-P, 2SB944-Q, 2SB945, 2SB945-P, 2SB945-Q, 2SB945-R, 2SB946, 2SB946-P, 2SB946-Q, 2SB946-R, 2SB950A, 2SB950A-P, 2SB950A-Q, 2SB951A, 2SB951A-P, 2SB951A-Q, 2SB992, 2SB992-O, 2SB992-Y, 2SB995, 2SB995-O, 2SB995-R, 2SB995-Y, 2SB996, 2SB996-O, 2SB996-R, 2SB996-Y, BD244B, BD244C, BD538, BD538J, BD538K, BD540B, BD540C, BD544B, BD544C, BD546B, BD546C, BD648, BD650, BD652, BD710, BD712, BD744B, BD744C, BD800, BD802, BD810, BD900, BD900A, BD902, BD910, BD912, BD952, BD954, BD956, BDT42B, BDT42BF, BDT42C, BDT42CF, BDT60A, BDT60B, BDT60C, BDT62A, BDT62B, BDT62C, BDT64A, BDT64B, BDT64C, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT94, BDT94F, BDT96, BDT96F, BDW24B, BDW24C, BDW46, BDW46G, BDW47, BDW47G, BDW48, BDW54B, BDW54C, BDW54D, BDW64B, BDW64C, BDW64D, BDW74B, BDW74C, BDW74D, BDW94B, BDW94C, BDW94CF, BDX34B, BDX34BG, BDX34C, BDX34CG, BDX34D, BDX54B, BDX54BG, BDX54C, BDX54CG, BDX54D, BDX54E, BDX54F, BDX78, D44C10, D44C11, D44C12, D45C11, D45C12, D45H11, D45H11FP, KSA1010, KSA1010O, KSA1010R, KSA1010Y, KSB1017, KSB1017-O, KSB1017-R, KSB1017-Y, KSB596, KSB596-O, KSB596-R, KSB596-Y, KSB708, KSB708-O, KSB708-R, KSB708-Y, KTA1038, KTA1038-O, KTA1038-Y, KTA1049, KTA1049O, KTA1049Y, KTB1367, KTB1367O, KTB1367R, KTB1367Y, KTB1368, KTB1368O, KTB1368R, KTB1368Y, MJE15029, MJE15029G, MJE15031, MJE15031G, MJE5170, MJE5171, MJE5172, MJE702T, MJE703T, MJF127, MJF127G, MJF15031, MJF15031G, MJF2955, MJF2955G, MJF6668, MJF6668G, NTE153, NTE292, TIP106, TIP106G, TIP107, TIP107G, TIP126, TIP126G, TIP127, TIP127G, TIP136, TIP136G, TIP137, TIP137G, TIP146T, TIP147T, TIP42B, TIP42BG, TIP42C, TIP42CF, TIP42CG, TTA1452B, TTB1020B or TTB1452B.
