Here is an image showing the pin diagram of this transistor.The KSA1220 transistor can have a current gain of 60 to 320. The gain of the KSA1220-O will be in the range from 100 to 200, for the KSA1220-R it will be in the range from 60 to 120, for the KSA1220-Y it will be in the range from 160 to 320.The complementary NPN transistor to the KSA1220 is the KSC2690.You can replace the KSA1220 with the 2SA1021, 2SA1220, 2SA1220A, 2SB649 or KSA1220A.
