The 2SB564A 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 2SB564A transistor can have a current gain of 70 to 400. The gain of the 2SB564AGR will be in the range from 200 to 400, for the 2SB564AO it will be in the range from 70 to 140, for the 2SB564AY it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SB564A might only be marked "B564A".The complementary NPN transistor to the 2SB564A is the 2SD471A.The 2SA1588 (SOT-323), KTA1505 (SOT-23) and KTA1505S (SOT-23) is the SMD version of the 2SB564A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSB564A, KSB564AC is the TO-92 version of the 2SB564A.You can replace the 2SB564A with the KSB564A, MPS6651, MPS6651G, MPS6652, MPS6652G, MPSW51, MPSW51A, MPSW51AG or MPSW51G.
