Pinout of 2SB564

The 2SB564 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.

Classification of hFE

The 2SB564 transistor can have a current gain of 90 to 400. The gain of the 2SB564K will be in the range from 200 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.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SB564 might only be marked "B564".

Complementary NPN transistor

The complementary NPN transistor to the 2SB564 is the 2SD471.

SMD Version of 2SB564 transistor

The 2SA1588 (SOT-323), KTA1505 (SOT-23) and KTA1505S (SOT-23) is the SMD version of the 2SB564 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.

Replacement and Equivalent for 2SB564 transistor

You can replace the 2SB564 with the 2N4954, 2SB598, KSB564AC or KSB811.
