What is the differences between base and alkali?

Compare and explain the differences in Ic (collector current) and collector base junction leakage current ?

• comparison between collector current and collector base junction leakage current,

• Answer:

  Ic is the operating current of the transistor, and usually is in the mA range, although with power devices it can be in the amps. The value of the current is determined by the transistor and the bias circuit. ICBO, C-B leakage current, is leakage current with the emitter open, and is in the nA range for most devices, close to zero. It is very temperature sensitive, and is determined by the voltage VCBO, temperature, and device construction. It is a quality factor, ie, the lower the value the better the quality of the transistor. High values are due to contamination or other problems.
