Mica Insulating Sheet for TO-3 Transistor – 29x42x0.12mm – 1 Piece
Original price was: 1.00 EGP.0.70 EGPCurrent price is: 0.70 EGP.

The BC639 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 the this transistor.

The complementary?PNP?transistor to the BC639 is the?BC640.
You can replace the BC639 with the?KSC1009C
