Here is an image showing the pin diagram of this transistor.The 2SB825-S transistor can have a current gain of 140 to 280. The gain of the 2SB825 will be in the range from 70 to 280, for the 2SB825-Q it will be in the range from 70 to 140, for the 2SB825-R it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB825-S might only be marked "B825-S".The complementary NPN transistor to the 2SB825-S is the 2SD1061-S.You can replace the 2SB825-S with the 2SA1290, 2SA1290-S, 2SA1291, 2SA1291-S, 2SA1470, 2SA1470-S, 2SA1471, 2SA1471-S, 2SA1742, 2SA1743, 2SA1744, 2SB1135, 2SB1135-S, 2SB1136, 2SB1136-S, 2SB826, 2SB826-S, BD204, BD304, BD536, BD538, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDX78, D45H11, D45H11FP or D45H8.
