BC548 NPN Transistor

Description

BC548 Bipolar Transistor Characteristics of the BC548 bipolar transistor Type -?NPN Collector-Emitter Voltage:?30?V Collector-Base Voltage:?30?V Emitter-Base Voltage:?5?V Collector Current:?0.1?A Collector Dissipation -?0.5?W DC Current Gain (hfe) -?110?to?800 Transition Frequency -?150?MHz Noise Figure -?2?dB Operating and Storage Junction Temperature Range?-65 to 150??C Package -?TO-92 Pin configuration (Pinout) of the BC548 The BC548 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 collector, base, and emitter leads. Here is an image showing the pin diagram of the this transistor. Classification of hFE The BC548 transistor might have a current gain anywhere between?110?and?800.
