How much voltage does a transistor use?
Note in the formula above, that VBE(sat) is the required base voltage that must be present in order to forward-bias the transistor’s base/emitter junction (i.e., to turn the transistor on). Generally speaking, this value is between . 6 to . 7 volts for a general-purpose transistor.
What is the junction of a transistor?
Solution: A junction transistor comprises three regions – emitter, base, and collector. The emitter is on one side of the transistor. It is moderate in size and heavily doped. Also, it supplies a large number of majority charge carriers.
What is the voltage between base and collector?
The first spec, VCBO, states that the maximum voltage that can be applied from the collector to the base is 50 V. The Collector−Emitter Voltage, VCEO, spec states the maximum voltage that can be applied from the collector to emitter is 50 V.
What is the maximum voltage that a junction can withstand?
The maximum allowable voltage that a junction of a transistor can withstand is called the breakdown voltage rating. The V CEO rating which you see in a transistor datasheet is the breakdown voltage rating for the collector-emitter junction of the transistor.
What is the breakdown voltage of a transistor?
The V EBO rating which you see in a transistor datasheet is the breakdown voltage rating for the emitter-base junction of the transistor. Again, this voltage must be checked on the transistor’s datasheet to make sure it is not exceeded.
What is the base voltage of a silicon transistor?
If the transistor is made up of a silicon material, the base-emitter voltage (VBE) will be 0.7 V. If the transistor is made up of a germanium material, the base-emitter voltage (VBE) will be 0.3 V. Collector-base voltages (VCB) for npn and pnp transistors
Which is the active region of a transistor?
The transistor is normally operated in the active region for amplifying the electric current. In active region, the emitter junction (JE) is forward biased and the collector junction (JC) is reverse biased. The typical base-emitter voltages (VBE) for both npn and pnp transistors are as follows:
