The KSP8099 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 KSP8099C transistor (with suffix "C") is the center collector version of the KSP8099.
Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the KSP8099 is the KSP8599.The 2SC3438 (SOT-89), FMMTA06 (SOT-23), KST06 (SOT-23), MMBTA06 (SOT-23), PMBTA06 (SOT-23), PZTA06 (SOT-223) and SMBTA06 (SOT-23) is the SMD version of the KSP8099 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSP8099 with the 2N5830, 2SC1009, BC538, KSC1009, KSP06, MPS8099, MPS8099G, MPSA06, MPSA06G, MPSW06, MPSW06G, PN4033, ZTX454 or ZTX455.
