The 2SB564AY 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.
Here is an image showing the pin diagram of this transistor.The 2SB564AY transistor can have a current gain of 120 to 240. The gain of the 2SB564A will be in the range from 70 to 400, for the 2SB564AGR it will be in the range from 200 to 400, for the 2SB564AO it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SB564AY might only be marked "B564AY".The complementary NPN transistor to the 2SB564AY is the 2SD471AY.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 2SB564AY transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSB564ACY, KSB564AY is the TO-92 version of the 2SB564AY.You can replace the 2SB564AY with the KSB564A, KSB564AY, M8550, MPS6651, MPS6651G, MPS6652, MPS6652G, MPS750, MPS750G, MPS8550, MPSW51, MPSW51A, MPSW51AG, MPSW51G, SS8550, ZTX549, ZTX550 or ZTX949.
