What can damage a transistor?
Sometimes external causes may damage or even destroy transistors. Bad handling of FETs can lead to damage by electrostatic discharge. Sometimes this will result in a transistor (or a circuit board) not working when fitted within a system.
How much voltage can a transistor handle?
The diode only needs 0.6V to turn on, more voltage than that means more current. Some transistors may only be rated for a maximum of 10-100mA of current to flow through them.
How much voltage is needed to turn on a transistor?
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.
Can a transistor handle 12V?
Vload = 12V In general, we can use both PNP or NPN transistors as switches. However, PNP transistors can only control the same voltage as is supplied to the Arduino chip.
How much current is needed to turn on BJT?
The Vb threshold for many BJTs is about 0.7V, meaning that at that voltage they begin to open. Also, the nature of BJTs is that while you will need a minimum of about 0.7V to turn it on, the current through the base is the defining factor for performance. As the base current increases, so does the collector current.
How much current is needed to activate a transistor?
The diode only needs 0.6V to turn on, more voltage than that means more current. Some transistors may only be rated for a maximum of 10-100mA of current to flow through them. If you supply a current over the maximum rating, the transistor might blow up.
What is a BJT transistor?
Transistors: Bipolar Junction Transistors (BJT) General configuration and definitions The transistor is the main building block “element” of electronics. It is a semiconductor device and it comes in two general types: the Bipolar Junction Transistor (BJT) and the Field Effect Transistor (FET).
What is common emitter configuration in BJT?
Common Emitter Configuration – shows both Current and Voltage Gain. Common Collector Configuration – shows Current Gain but no Voltage Gain. In a common base mode which is also called grounded base, the base terminal of the BJT is used as the common terminal for both input and output of the configuration.
What is a bipolar junction transistor?
A Bipolar Junction Transistor is a three layer (npn or pnp) semiconductor device. There are two pn junctions in the transistor. The three layers are called the emitter, base and collector.
