Here is an image showing the pin diagram of this transistor.The KSB744A transistor can have a current gain of 60 to 320. The gain of the KSB744A-O will be in the range from 100 to 200, for the KSB744A-R it will be in the range from 60 to 120, for the KSB744A-Y it will be in the range from 160 to 320.The complementary NPN transistor to the KSB744A is the KSD794A.You can replace the KSB744A with the 2SB744A, BD190, MJE235, MJE252 or MJE254.
