The 2SB564K 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, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SB564K transistor can have a current gain of 200 to 400. The gain of the 2SB564 will be in the range from 90 to 400, for the 2SB564L it will be in the range from 135 to 270, for the 2SB564M it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SB564K might only be marked "B564K".The complementary NPN transistor to the 2SB564K is the 2SD471K.The 2SA1588 (SOT-323), 2SA1588-GR (SOT-323), BC808 (SOT-23), BC808-25 (SOT-23), BC808-25W (SOT-323), BC808W (SOT-323), FMMT549A (SOT-23), KTA1505 (SOT-23), KTA1505GL (SOT-23), KTA1505S (SOT-23) and KTA1505S-GL (SOT-23) is the SMD version of the 2SB564K transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB564K with the 2N4953, 2N4954, 2SA1382, 2SA1680, 2SA1761, 2SB1116, 2SB1116-K, 2SB1229, 2SB1229-T, 2SB598, 2SB892, 2SB892-T, 2SB985, 2SB985T, KSB1116, KSB1116-G, KSB1116S, KSB1116S-G, KSB564AC, KSB564ACG, KSB811 or KSB811-G.
