How is the power rating of a transistor calculated?
Power rating of the transistor is independent of the resistor. The power dissipated by the transistor is Pd = Vce x Ic. So, the product of the current flowing through the transistor multiplied by the voltage across its emitter and collector will define the power it dissipates. This is the steady state power.
Does transistor consume current?
Power dissipation When a transistor conducts current between collector and emitter, it also drops voltage between those two points. At any given time, the power dissipated by a transistor is equal to the product of collector current and collector-emitter voltage.
What is the V CEO rating of a transistor?
The V CEO Rating of a Transistor is the maximum allowable voltage that the collector-emitter junction of a transistor can handle before it becomes damaged or destroyed. The maximum allowable voltage that a junction of a transistor can withstand is called the breakdown voltage rating.
What is the Vceo rating of a transistor?
The VCEO Rating of a Transistor is the maximum allowable voltage that the collector-emitter junction of a transistor can handle before it becomes damaged or destroyed. The maximum allowable voltage that a junction of a transistor can withstand is called the breakdown voltage rating.
What is the maximum collector current rating of a transistor?
Understand that this maximum figure assumes a saturated state (minimum collector-emitter voltage drop). If the transistor is not saturated and is dropping substantial voltage between collector and emitter, the maximum power dissipation rating will probably be exceeded before the maximum collector current rating.
What is the Vebo rating of a transistor?
The VEBO Rating of a Transistor is the maximum allowable voltage that the emitter-base junction of a transistor can handle before it becomes damaged or destroyed. The VEBO rating which you see in a transistor datasheet is the breakdown voltage rating for the emitter-base junction of the transistor.
