The KSB564AO 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 KSB564ACO transistor (with suffix "C") is the center collector version of the KSB564AO. Here is an image showing the pin diagram of this transistor.
Classification of hFE
The KSB564AO transistor can have a current gain of 70 to 140. 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 KSB564AY it will be in the range from 120 to 240.
SMD Version of KSB564AO transistor
The 2SA1182 (SOT-23), 2SA1182-O (SOT-23), 2SA1588 (SOT-323), 2SA1588-O (SOT-323), FJX1182 (SOT-323), FJX1182-O (SOT-323), KSA1182 (SOT-23), KSA1182-O (SOT-23), KTA1505 (SOT-23), KTA1505O (SOT-23), KTA1505S (SOT-23) and KTA1505S-O (SOT-23) is the SMD version of the KSB564AO transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
