The ZTX549 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.
Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the ZTX549 is the ZTX449.The 2SA1036 (SOT-23), 2SA1204 (SOT-89), 2SA1588 (SOT-323), 2SA1621 (SOT-23), FMMT549 (SOT-23), KTA1298 (SOT-23), KTA1505 (SOT-23), KTA1505S (SOT-23), KTA1664 (SOT-89) and KTC8550S (SOT-23) is the SMD version of the ZTX549 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the ZTX549 with the BC527, MPS4354, MPS4355, MPS6652, MPS6652G, MPS750, MPS750G, MPS751, MPS751G, MPSW51, MPSW51A, MPSW51AG, MPSW51G, ZTX550, ZTX949 or ZTX951.
