The KSC1506-O 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 KSC1506-O transistor can have a current gain of 70 to 140. The gain of the KSC1506 will be in the range from 40 to 240, for the KSC1506-R it will be in the range from 40 to 80, for the KSC1506-Y it will be in the range from 120 to 240.The 2SC4497 (SOT-23), 2SC4497-O (SOT-23), BF620 (SOT-89), BF820 (SOT-23) and PMBTA42 (SOT-23) is the SMD version of the KSC1506-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC1506-O with the 2N6517C, 2SC2271, 2SC2482, 2SC2551, 2SC2551-O, 2SC3468, KSC2330 or KSC2330O.
