The BC321C 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 BC321C transistor can have a current gain of 420 to 800. The gain of the BC321 will be in the range from 110 to 800, for the BC321A it will be in the range from 110 to 220, for the BC321B it will be in the range from 200 to 450.The complementary NPN transistor to the BC321C is the BC318C.You can replace the BC321C with the BC317, BC317C, BC318, BC318C, BC320, BC320C, KSP55, KTC9015, MPS6535, MPS6652, MPS6652G, MPS750, MPS750G, MPS751, MPS751G, MPSA55, MPSA55G, MPSW51, MPSW51A, MPSW51AG, MPSW51G, MPSW55, MPSW55G or ZTX790A.
