Here is an image showing the pin diagram of this transistor.The 2SC594-R transistor can have a current gain of 40 to 80. The gain of the 2SC594 will be in the range from 40 to 240, for the 2SC594-O it will be in the range from 70 to 140, for the 2SC594-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC594-R might only be marked "C594-R".The complementary PNP transistor to the 2SC594-R is the 2SA594-R.The 2SC3803 (SOT-89) and 2SC3803-R (SOT-89) is the SMD version of the 2SC594-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC594-R with the 2N1480, 2N1482, 2N1613, 2N1893, 2N3020, 2N3108, 2N4030, 2N4031, 2N4238, 2N4239, 2N5152, 2N5321, 2N5334, 2N5335, 2N5336, 2SC108A, 2SC108A-R, 2SC109A, 2SC109A-R, 2SC503, 2SC503-R, 2SC504, 2SC504-R, 2SC512, 2SC512-R, BC141, BC141-6, BC300, BC300-4, BC301, BC301-4, BC302, BC302-4 or BC441.
