The KSB564AY is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads. The KSB564ACY transistor (with suffix "C") is the center collector version of the KSB564AY.
Here is an image showing the pin diagram of this transistor.The KSB564AY transistor can have a current gain of 120 to 240. The gain of the KSB564A will be in the range from 70 to 400, for the KSB564AG it will be in the range from 200 to 400, for the KSB564AO it will be in the range from 70 to 140.The complementary NPN transistor to the KSB564AY is the KSD471AY.The 2SA1182 (SOT-23), 2SA1182-Y (SOT-23), 2SA1204 (SOT-89), 2SA1298 (SOT-23), 2SA1588 (SOT-323), 2SA1588-Y (SOT-323), 2SA1621 (SOT-23), 2SB766 (SOT-89), 2SB766-R (SOT-89), BC808 (SOT-23), BC808-16 (SOT-23), BC808-16W (SOT-323), BC808W (SOT-323), FJX1182 (SOT-323), FJX1182-Y (SOT-323), FMMT549 (SOT-23), KSA1182 (SOT-23), KSA1182-Y (SOT-23), KSA1298 (SOT-23), KTA1298 (SOT-23), KTA1505 (SOT-23), KTA1505S (SOT-23), KTA1505S-Y (SOT-23), KTA1505Y (SOT-23), KTA1664 (SOT-89) and KTC8550S (SOT-23) is the SMD version of the KSB564AY transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SB564AY is the TO-92 version of the KSB564AY.You can replace the KSB564AY with the 2SB564A, 2SB564AY, M8550, MPS6651, MPS6651G, MPS6652, MPS6652G, MPS750, MPS750G, MPS8550, MPSW51, MPSW51A, MPSW51AG, MPSW51G, SS8550, ZTX549, ZTX550 or ZTX949.
