BC547 Specs
Type: The BC547 is an NPN transistor, implying that it operates with a positive voltage at the collector concerning the emitter.
Package Type: The BC547 comes in a TO-92 package, which is a common through-hole package featuring three leads for easy PCB mounting.
Collector-Emitter Voltage (VCEO): The maximum voltage that can be applied between the collector and emitter without causing damage to the transistor. For BC547, the VCEO is typically rated at 45V.
Collector-Base Voltage (VCBO): This specification indicates the maximum voltage that can be applied between the collector and base without causing damage. BC547 typically has a VCBO rating of 50V.
Emitter-Base Voltage (VEBO): The maximum voltage that can be applied between the emitter and base without causing damage. The VEBO for BC547 is generally around 6V.
Collector Current (IC): BC547 can handle a maximum continuous collector current of 100mA. This rating defines the current-carrying capacity of the transistor.
Power Dissipation (Ptot): This specification represents the maximum power the transistor can dissipate without exceeding its temperature limits. The BC547 can handle a maximum power dissipation of 500mW.
Transition Frequency (fT): The BC547 typically has a transition frequency of 150MHz, indicating its high-frequency performance, making it suitable for amplifier applications.
Collector-Emitter Saturation Voltage (VCE(sat)): The VCE(sat) is the voltage drop across the collector-emitter junction when the transistor is fully saturated. BC547 exhibits a low VCE(sat), making it efficient in switching applications.
Base-Emitter Voltage (VBE): The voltage drop between the base and emitter when a current flows through the base terminal. BC547 typically has a VBE of around 0.65V at a base current of 10mA.
