The KSA539CR 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. Suffix "C" means center collector in KSA539R.
Here is an image showing the pin diagram of this transistor.The KSA539CR transistor can have a current gain of 40 to 80. The gain of the KSA539C will be in the range from 40 to 240, for the KSA539CO it will be in the range from 70 to 140, for the KSA539CY it will be in the range from 120 to 240.The complementary NPN transistor to the KSA539CR is the KSC815CR.The 2SA1483 (SOT-89), 2SA1483-R (SOT-89), FJX733 (SOT-323) and FJX733R (SOT-323) is the SMD version of the KSA539CR transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSA539CR with the BC636, BC638, BC640, KSA708C, KSA708CR, KSA931 or KSA931R.
