BC639 NPN Transistor

BC639 Bipolar Transistor Characteristics of the BC639 bipolar transistor Type -? NPN Collector-Emitter Voltage:? 80 ?V Collector-Base Voltage:? 80 ?V Emitter-Base Voltage:? 5 ?V Collector Current:? 0.5 ?A Collector Dissipation -? 0.625 ?W DC Current Gain (h fe ) -? 40 ?to? 160 Transition Frequency -? 200 ?MHz Operating and Storage Junction Temperature Range? -55 to 150 ??C Package -? TO-92 Pin configuration (Pinout) of the BC639 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. Complementary PNP transistor The complementary? PNP ?transistor to the BC639 is the?BC640. Replacement and equivalent transistor for the BC639 You can replace the BC639 with the?KSC1009C
