Here is an image showing the pin diagram of this transistor.The KSB744 transistor can have a current gain of 60 to 320. The gain of the KSB744-O will be in the range from 100 to 200, for the KSB744-R it will be in the range from 60 to 120, for the KSB744-Y it will be in the range from 160 to 320.The complementary NPN transistor to the KSB744 is the KSD794.You can replace the KSB744 with the 2SB744, 2SB744A, BD132, BD188, BD190, KSB744A, MJE235 or MJE252.
