Here is an image showing the pin diagram of this transistor.The 2SB994 transistor can have a current gain of 60 to 200. The gain of the 2SB994-O will be in the range from 60 to 120, for the 2SB994-Y it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB994 might only be marked "B994".The complementary NPN transistor to the 2SB994 is the 2SD1354.You can replace the 2SB994 with the 2SA1010, 2SA1077, 2SA1262, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA489, 2SA768, 2SA769, 2SA770, 2SA771, 2SB1015, 2SB1016, 2SB1017, 2SB1090, 2SB1097, 2SB1187, 2SB1366, 2SB1367, 2SB1368, 2SB507, 2SB566A, 2SB595, 2SB596, 2SB633, 2SB703, 2SB703A, 2SB707, 2SB708, 2SB747, 2SB761, 2SB761A, 2SB762, 2SB762A, 2SB834, 2SB858, 2SB870, 2SB942, 2SB942A, 2SB945, 2SB946, 2SB995, 2SB996, BD204, BD242A, BD242B, BD242C, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BD936, BD936F, BD938, BD938F, BD940, BD940F, BD942, BD942F, BD950, BD952, BD954, BD956, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT92, BDT92F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, KSA1010, KSB1015, KSB1017, KSB1097, KSB596, KSB707, KSB708, KSB834, KTB1366, KTB1367, KTB1368, KTB988, MJE15029, MJE15029G or NTE153.
