Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD244A is the BD243A.The 2STF2360 (SOT-89), 2STN2360 (SOT-223), BDP950 (SOT-223), NZT660A (SOT-223) and STN951 (SOT-223) is the SMD version of the BD244A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD244A with the 2N6040, 2N6040G, 2N6041, 2N6041G, 2N6042, 2N6042G, 2N6107, 2N6107G, 2N6110, 2N6667, 2N6667G, 2N6668, 2N6668G, 2SA1010, 2SA1010K, 2SA1010L, 2SA1010M, 2SA1077, 2SA1290, 2SA1290-Q, 2SA1290-R, 2SA1290-S, 2SA1291, 2SA1291-Q, 2SA1291-R, 2SA1291-S, 2SA1329, 2SA1329-O, 2SA1329-Y, 2SA1452, 2SA1452-O, 2SA1452-Y, 2SA1452A, 2SA1452A-O, 2SA1452A-Y, 2SA1470, 2SA1470-Q, 2SA1470-R, 2SA1470-S, 2SA1471, 2SA1471-Q, 2SA1471-R, 2SA1471-S, 2SA1725, 2SA1725-O, 2SA1725-P, 2SA1725-Y, 2SA1726, 2SA1726-O, 2SA1726-P, 2SA1726-Y, 2SA1742, 2SA1742-K, 2SA1742-L, 2SA1742-M, 2SA1743, 2SA1743-K, 2SA1743-L, 2SA1743-M, 2SA1744, 2SA1744-K, 2SA1744-L, 2SA1744-M, 2SA770, 2SA771, 2SB1018, 2SB1018-O, 2SB1018-Y, 2SB1018A, 2SB1018A-O, 2SB1018A-Y, 2SB1020, 2SB1020A, 2SB1097, 2SB1097-K, 2SB1097-L, 2SB1097-M, 2SB1224, 2SB1225, 2SB1228, 2SB1626, 2SB1626-O, 2SB1626-P, 2SB1626-Y, 2SB633, 2SB633-C, 2SB633-D, 2SB633-E, 2SB633-F, 2SB673, 2SB674, 2SB675, 2SB707, 2SB707-O, 2SB707-R, 2SB707-Y, 2SB708, 2SB708-O, 2SB708-R, 2SB708-Y, 2SB870, 2SB870-P, 2SB870-Q, 2SB870-R, 2SB881, 2SB882, 2SB886, 2SB946, 2SB946-P, 2SB946-Q, 2SB946-R, 2SB951, 2SB951-P, 2SB951-Q, 2SB951A, 2SB951A-P, 2SB951A-Q, 2SB992, 2SB992-O, 2SB992-Y, BD204, BD244B, BD244C, BD304, BD536, BD536J, BD536K, BD538, BD538J, BD538K, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD646, BD648, BD650, BD652, BD798, BD800, BD802, BD808, BD810, BD898, BD898A, BD900, BD900A, BD902, BDT62, BDT62A, BDT62B, BDT62C, BDT64, BDT64A, BDT64B, BDT64C, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDW24A, BDW24B, BDW24C, BDW45, BDW46, BDW46G, BDW47, BDW47G, BDW48, BDW64A, BDW64B, BDW64C, BDW64D, BDW74A, BDW74B, BDW74C, BDW74D, BDW94A, BDW94B, BDW94C, BDW94CF, BDX34A, BDX34B, BDX34BG, BDX34C, BDX34CG, BDX34D, BDX54A, BDX54B, BDX54BG, BDX54C, BDX54CG, BDX54D, BDX78, D45H11, D45H11FP, D45H8, KSA1010, KSA1010O, KSA1010R, KSA1010Y, KSB1097, KSB1097-O, KSB1097-R, KSB1097-Y, KSB707, KSB707-O, KSB707-R, KSB707-Y, KSB708, KSB708-O, KSB708-R, KSB708-Y, MJE15029, MJE15029G, MJF6668, MJF6668G, NTE197, TIP105, TIP105G, TIP106, TIP106G, TIP107, TIP107G, TIP135, TIP135G, TIP136, TIP136G, TIP137, TIP137G, TIP145T, TIP146T, TIP147T, TTA1452B, TTB1020B or TTB1452B.Same transistor is also available in:
